JavaScript
You are an expert in JavaScript, React, Node.js, Next.js App Router, Zustand, Shadcn UI, Radix UI, Tailwind, and Stylus.

Code Style and Structure

- Write concise, technical JavaScript code following Standard.js rules.
- Use functional and declarative programming patterns; avoid classes.
- Prefer iteration and modularization over code duplication.
- Use descriptive variable names with auxiliary verbs (e.g., isLoading, hasError).
- Structure files: exported component, subcomponents, helpers, static content.
- never use TypeScript or create a .ts files use js and jsx

Standard.js Rules

- Use 2 space indentation.
- Use single quotes for strings except to avoid escaping.
- No semicolons (unless required to disambiguate statements).
- No unused variables.
- Add a space after keywords.
- Add a space before a function declaration's parentheses.
- Always use === instead of ==.
- Infix operators must be spaced.
- Commas should have a space after them.
- Keep else statements on the same line as their curly braces.
- For multi-line if statements, use curly braces.
- Always handle the err function parameter.
- Use camelcase for variables and functions.
- Use PascalCase for constructors and React components.

Naming Conventions

- Use lowercase with dashes for directories (e.g., components/auth-wizard).
- Favor named exports for components.

React Best Practices

- Use functional components with prop-types for type checking.
- Use the "function" keyword for component definitions.
- Implement hooks correctly (useState, useEffect, useContext, useReducer, useMemo, useCallback) and use "use client" for client components.
- Follow the Rules of Hooks (only call hooks at the top level, only call hooks from React functions).
- Create custom hooks to extract reusable component logic.
- Use React.memo() for component memoization when appropriate.
- Implement useCallback for memoizing functions passed as props.
- Use useMemo for expensive computations.
- Avoid inline function definitions in render to prevent unnecessary re-renders.
- Prefer composition over inheritance.
- Use children prop and render props pattern for flexible, reusable components.
- Implement React.lazy() and Suspense for code splitting.
- Use refs sparingly and mainly for DOM access.
- Prefer controlled components over uncontrolled components.
- Implement error boundaries to catch and handle errors gracefully.
- Use cleanup functions in useEffect to prevent memory leaks.
- Use short-circuit evaluation and ternary operators for conditional rendering.

State Management

- Use Zustand for global state management.
- Lift state up when needed to share state between components.
- Use context for intermediate state sharing when prop drilling becomes cumbersome.

UI and Styling

- Use Shadcn UI for component foundations.
- Implement responsive design with Tailwind CSS; use a mobile-first approach.
- Use Tailwind for utility classes and rapid prototyping.
- Combine Tailwind utility classes with Stylus modules for a hybrid approach:
  - Use Tailwind for common utilities and layout.
  - Use Stylus modules for complex, component-specific styles.
  - Never use the @apply directive
  - Always add the import for the component you are using

Performance Optimization

- Minimize 'use client', 'useEffect', and 'useState'; favor React Server Components (RSC).
- Wrap client components in Suspense with fallback.
- Use dynamic loading for non-critical components.
- Optimize images: use WebP format, include size data, implement lazy loading.
- Implement route-based code splitting in Next.js.
- Minimize the use of global styles; prefer modular, scoped styles.
- Use PurgeCSS with Tailwind to remove unused styles in production.

Forms and Validation

- Use controlled components for form inputs.
- Implement form validation (client-side and server-side).
- Consider using libraries like react-hook-form for complex forms.
- Use Zod or Joi for schema validation.

Error Handling and Validation

- Prioritize error handling and edge cases.
- Handle errors and edge cases at the beginning of functions.
- Use early returns for error conditions to avoid deeply nested if statements.
- Place the happy path last in the function for improved readability.
- Avoid unnecessary else statements; use if-return pattern instead.
- Use guard clauses to handle preconditions and invalid states early.
- Implement proper error logging and user-friendly error messages.
- Model expected errors as return values in Server Actions.

Accessibility (a11y)

- Use semantic HTML elements.
- Implement proper ARIA attributes.
- Ensure keyboard navigation support.

Testing

- Write unit tests for components using Jest and React Testing Library.
- Implement integration tests for critical user flows.
- Use snapshot testing judiciously.

Security

- Sanitize user inputs to prevent XSS attacks.
- Use dangerouslySetInnerHTML sparingly and only with sanitized content.

Internationalization (i18n)

- Use libraries like react-intl or next-i18next for internationalization.

Key Conventions

- Use 'nuqs' for URL search parameter state management.
- Optimize Web Vitals (LCP, CLS, FID).
- Limit 'use client':
  - Favor server components and Next.js SSR.
  - Use only for Web API access in small components.
  - Avoid for data fetching or state management.
- Balance the use of Tailwind utility classes with Stylus modules:
  - Use Tailwind for rapid development and consistent spacing/sizing.
  - Use Stylus modules for complex, unique component styles.

Follow Next.js docs for Data Fetching, Rendering, and Routing.

  - Use lowercase with dashes for directory names (e.g., `components/auth-wizard`).

- **Exports:**
  - Favor named exports for components to improve clarity and maintainability.

## TypeScript Usage

- **Interfaces Over Types:**
  - Prefer using `interface` for defining object shapes.

When updating resume templates

## Introduction

**What is a resume?**

Your resume is essentially a 30-second elevator pitch on paper, encapsulating your contact information, education, experience, and background. Its purpose is to convince the hiring team to interview you.

Understanding your target audience is crucial. We wrote this wiki to describe what happens to your resume once it’s submitted, and [what the hiring process looks like from the employer’s perspective](https://thetechresume.com/samples/the-hiring-pipeline). The suggestions made in this wiki are made with this in mind, and we encourage applicants to be strategic with how they craft their resumes.

Ultimately, your resume can only do so much if you don’t have **genuine, relevant experience**.

For students, it's imperative to use your time in college wisely, engaging in meaningful activities such as projects, involvement in engineering teams, participation in research groups, and securing internships. These experiences significantly bolster the substance of your resume.

## General Rules

### Make your resume easy to read and skim

1. Use a single-column layout like <https://imgur.com/LC6AS8r>
2. Avoid icons, images, and graphics.
3. Don't indent your sections and bullet points. Using bullet points inherently creates indentation <https://imgur.com/qBJjbth>
4. Use bullet points, not paragraphs.
5. Use a modern, easy-to-read font like Calibri, Bitstream Charter, or Arial.
6. Use a black (not thin) font with at least 10.5+ font size.
7. Don't [justify your text](https://uit.stanford.edu/accessibility/concepts/typography#justifyText) since it creates inconsistent spacing between words <https://imgur.com/6eKsENw>
8. Ensure you have enough white space. No cramming. Use sufficient margins (minimum 0.4 inches) and line spacing (minimum 1.07).
9. Avoid excessive *italicization*, **bolding**, and ALL CAPS. If you do use one, use it independently of each other. 
10. Have clear section separation. The reader should be able to easily distinguish sections from others.
11. One page long, unless you have some 10+ years of experience. The rule of thumb is 1 page per decade of experience.
12. Separate your skills using **commas** <https://imgur.com/wzvRAfB>

### Make your resume more effective

We will dive deeper into this later in the wiki, but generally:

1. Include relevant and technical details to showcase your qualifications and distinguish yourself from other candidates. We will mention the [STAR/CAR/XYZ bullet point methods later in the wiki](https://old.reddit.com/r/EngineeringResumes/wiki/index#wiki_each_bullet_point_should_follow_star.2C_xyz.2C_or_car).
2. Provide context and incorporate relevant keywords. This helps the hiring team understand and relate to your work and technical achievements.
3. Avoid adding unnecessary information that doesn’t add to your candidacy.
4. Bring your critical and pertinent details to the top and the left of the resume. This increases the odds of these details being read by the hiring team.

As stated earlier, a resume functions as a 30-second elevator pitch on paper. Therefore, it needs to be succinct, easy to follow, yet informative for it to be effective. Following the rules above will:

1. Make your resume less distracting so the reader can easily locate and focus on the important details.
2. Increase the amount of white space available so you can include more content that improves your candidacy.
3. Prevent your resume from being a wall of text that makes it hard to read.

### Keep it to 1 page

A common question we get is why we don’t recommend having multiple pages. Here’s why: 

* The majority of resumes that are posted on this sub don't need a second page. Once it gets cleaned up (content and format), a lot of people will have trouble populating 1 page with relevant, technical content.
* A multi-page resume that is poorly formatted and filled with irrelevant information doesn’t give a good impression to the hiring team.
* The hiring team is going to spend far less effort on reading longer resumes.

As we keep stressing, the goal is to make your resume as easy to read as possible. If you’re having trouble doing this with 1 page, consider removing content that is less relevant to the role you’re applying to, even if it’s technical. You can add this to your portfolio instead.

If you decide to go with a second page, you should be in the position to at least be considered for a **senior/staff role**. These candidates will likely have enough relevant experience to justify a second page (or even more).

---

## Formatting

Your resume should be:

1. Easily _skimmable_ by recruiters, hiring managers, and interviewers
2. Easily _parsable_ by an Application Tracking System (ATS)

### [Recommended Templates](https://old.reddit.com/r/EngineeringResumes/wiki/templates)

/r/EngineeringResumes/wiki/templates

* [Google Docs](https://old.reddit.com/r/EngineeringResumes/wiki/templates#wiki_google_docs) <https://imgur.com/TraV3Qn>
* [LaTeX](https://old.reddit.com/r/EngineeringResumes/wiki/templates#wiki_latex) <https://imgur.com/LC6AS8r>

---

### [Accessibility](https://uit.stanford.edu/accessibility/concepts/typography)

* Use a modern, [easy-to-read](https://uit.stanford.edu/accessibility/concepts/typography#readableFonts) font like Calibri, Bitstream Charter, Arial, Lato, or Helvetica.
* Don't use grey-colored fonts since they're hard to read. Stick to black. Make sure to use a color that is printable in grey-scale. Be careful about using fonts that are too thin. Verify there is sufficient contrast with a white background.
* [Don't justify text](https://uit.stanford.edu/accessibility/concepts/typography#justifyText) since it causes inconsistent spacing between words. <https://imgur.com/6eKsENw>
* Don't italicize text since it can decrease the readability of your resume.
* Don't bold keywords within your bullet points, it's distracting.
* Italicization and bolding are only to be used if used _sparingly_. Excessive italicization and bolding decrease readability and ultimately contradict their purpose: **emphasis**.
* _Italicization_, ALL-CAPS, and **bolding**, if used, should be used independently of each other.
* Don't indent sections and bullet points. There's already indentation since the bullets themselves create an indent.
* Separate your sections clearly for optimal readability and visual clarity
  * Ensure there is sufficient and consistent white space between sections/subsections
  * Ensure there is sufficient and consistent white space between each job/project
  * Ensure there are sufficient vertical and horizontal margins (minimum 0.4 inches) <https://imgur.com/LC6AS8r>

---

### Dates

* If currently working at a job or on a project, use the word **Present** instead of ~~**Current**, **Now**~~, or ~~**Ongoing**~~
* If you choose to include months in addition to years, strictly use them and don't mix in ~~seasons~~ or ~~semesters~~ i.e. **March 2022**, not ~~Winter 2022~~
* Specific days of the year are unnecessary i.e. **January ~~1~~, 2023**
* Don't abbreviate years, i.e. **'23**. Denote the full year: **2023**
* Don't abbreviate months using digits, i.e. **9/2013**
  * If you choose to abbreviate your months, [follow the proper standard](https://web.library.yale.edu/cataloging/months)
  * Jan, Feb, Mar, Apr, May, **June**, **July**, Aug, **Sept**, Oct, Nov, Dec
  * Don't use periods when abbreviating months since they're unnecessary, i.e. **Sept** not **Sept.**
* For date ranges, use en dashes (–), not hyphens (-) or the word "to"
* Ensure there is a blank space before and after your en dashes i.e. **Mar 2012 – Mar 2022**, not **Mar 2012–Mar 2022**
* [Right align your dates to the right margin:](https://www.google.com/url?q=https://webapps.stackexchange.com/questions/51121/how-do-you-left-align-and-right-align-items-on-the-same-line-in-a-google-documen&sa=D&source=docs&ust=1704054021378265&usg=AOvVaw12Cc4WkVvDQM0Lz6rdHRwc) <https://imgur.com/87E2vkp>
* Your bullet points should not go further right than your dates <https://imgur.com/t1ZcrYR>

---

## Section Order

In general,

* [Once you've graduated from school and have started a full-time job](https://thetechresume.com/samples/resume-structure):
  * _Work Experience > Skills > Education_, or
  * _Skills > Work Experience > Education_
* If you're a student/new grad without much work experience:
  * _Education > Work Experience > Skills_, or
  * _Education > Work Experience > Projects (if you don't have sufficient work experience) > Skills_
* If you don't have any technical work experience:
  * _Education > Projects > Work Experience > Skills_
* If you don't have any work experience at all:
  * _Education > Projects > Volunteer Experience/Extracurriculars > Skills_

* Do **not** include a summary/profile unless you're a senior/staff engineer or above, making a career change, or addressing an unemployment gap/returning to the workforce
* Do **not** include a references section

---

## Contact Information

* **If you have a security clearance, it can be listed in the contact information section at the top of your resume near your name.**
  * Example: "Top Secret / SCI eligible with CI Polygraph"
* **If you have a foreign sounding name, or your education/work experience doesn't make it clear you're able to work in said country you're applying to, consider listing your citizenship/work visa status near your name to be explicitly clear to the recruiter/hiring manager that you don't require visa sponsorship.**
  * Example: "US Citizen", "US Permanent Resident", "Canadian Citizen", "Italian Citizen"
* Don't include your physical address and ZIP code
* Don't include your location (city, ST) unless the specific job you're applying for is in that specific city
  * Including a non-local location may cause implicit bias against you
* LinkedIn profiles are unnecessary
  * Chances are, nobody will ever click on your LinkedIn. If they want to find you on LinkedIn, they can simply search your name on LinkedIn or just Google you.
* Phone numbers are unnecessary
  * Interview processes these days don't begin with a cold call, the recruiter will email you for your phone number if they need it. Like location, a non-local area code may cause implicit bias against you
  * If you decide to list your phone number, don't preface your phone number with "Phone: ", "Cell: ", or "Mobile: "
  * If based in the US/Canada, omit the country code ~~+1~~, it's implied
* List only **1** email address
  * Use a modern email provider such as Gmail/Outlook, NOT AOL/Hotmail/Yahoo due to implicit bias against you
  * If you've already graduated, do not use a college email **unless** you went to a really prestigious school like MIT/CMU
* Don’t include a link to your GitHub profile if it’s empty
* Don't mask your email address, GitHub profile, and portfolio website i.e. [email](name@gmail.com), [github](github.com/username), [portfolio](myportfolio.com)
* Write out your email address, GitHub profile, and portfolio website in plain text i.e.
  * name@gmail.com
  * github.com/username
  * myportfolio.com
* Don't preface your email address with "Email: ". Simply display your email address i.e. name@gmail.com
* Don't preface your GitHub URL with "GitHub: ". Simply display 'github.com/username'
* Don't preface your personal website or portfolio URL with "Portfolio: ". Simply write out myportfolio.com for example
* Don't include https://www. for your URLs
* Don't underline, italicize, or color your email address/GitHub URL/portfolio URL/personal website URLs

---

## Work Experience

This section should be named _Work Experience_ or simply _Experience_ not ~~"Professional Experience", "Selected Experience", "Employment History", "Employment" or "Job History"~~

* Only include **PAID** work experience in this section (research experience can go here as well)
* Clearly indicate internships are internships and contract positions are contract positions
* Order positions and bullet points by relevancy to the job you’re interested in OR impressiveness: put your best stuff first!
* **Tailor your resume** for each application so it addresses the job description. Show that you can do the job
* **Add context**. Simply listing positions/projects and adding industry buzzwords is not enough. You need to tell hiring managers what you did and how you solved problems.
* **Differentiate yourself and don't be humble.** Simply listing job duties will not make your resume any different from others: [your resume is not your job description.](https://www.ag1source.com/2020/09/17/your-resume-is-not-your-job-description/). Tell us about your accomplishments, tangible metrics, and technical victories.
* **Avoid centering your skills around a piece of software if you can**. Any idiot can learn how to sketch, extrude, cut, and mate in SolidWorks - but identifying capabilities gaps (a need), creating a preliminary design, and taking it through the rest of the design process is something that fewer people can do, so try to focus on the engineering skills behind it. CAD and other software should be an “oh by the way” if possible.
* **Protip:** Engineers love it if you did hand-calc sanity checks instead of just hitting the RUN button in your FEA/CFD package, so do that and mention it at the interview. Seriously.
* Use bullet points, not paragraphs

If you're just graduating, focus more on showing a mastery of fundamental engineering skills first, then worry about the project management/leadership stuff if there is room left.

Not only are management & leadership very different in the real world, but no department in their right mind will have a new grad run a department or project or anything more complex than picking up lunch for the team. They are looking for someone who can master basic engineering tasks in this specific discipline and can hold a basic conversation. Show them you can do that first, and then think about running the show down the line.

### Bullet Points

#### Objectives

1. Highlight the technical work you did
2. Highlight technical challenges you faced and overcame
3. Highlight the impact of your work

---

#### General Rules

* Bullet points should be 1-2 lines long. Use [Quillbot](https://quillbot.com/) and [LanguageTool](https://languagetool.org/paraphrasing-tool) to help you [paraphrase and shorten your bullets](https://www.youtube.com/watch?v=VvPaEsuz-tY)
* Aim for **1** sentence per bullet
* Bullet points should be ordered from most relevant/impressive to least, as some hiring managers only have time to read the first they should get [THE BEST](https://media.giphy.com/media/VdVL5miirhFANoyPBM/giphy.gif)!
* Don't use [personal pronouns](https://www.grammarly.com/blog/personal-pronouns/) i.e. _I, we, us, my, our, their_
* Don't end bullet points with periods. Bullet points != sentences
* Your bullet points shouldn't go further right than your dates
* Don't spill bullets onto the following line with only 1–4 words on it. It's an extreme waste of space. For example <https://imgur.com/QCcZ792>
* Don't allow words to wrap to the next line and get hyphenated
* Avoid the excess use of **sub-bullet points**
  * They can clutter your resume, making it more verbose and harder to read
* Avoid using apostrophes **'**, ampersands **&**, and slashes **/**
* [Avoid the excessive use of adjectives and adverbs](https://resumeworded.com/resume-adverbs-key-advice), they're superfluous
  * B-adjectives: ~~excellent, innovative, expert, revolutionary, disruptive~~
  * B-adverbs: ~~creatively, diligently, meticulously, strategically, successfully, independently, innovatively, excellently, expertly~~
* Use digits instead of spelling out numbers: **8** ~~**eight**~~

---

#### Action Verbs

* Each bullet should begin with a **strong, past-tense action verb:**  
  https://web.archive.org/web/20240515003325/https://www.engineering.cornell.edu/sites/default/files/users/user240/Action%20Words%20for%20ENG%20(website).pdf

* **Led** is the past tense of **lead**
* **Good examples:** analyzed, architected, automated, built, created, decreased, designed, developed, implemented, improved, optimized, published, reduced, refactored
* **Bad examples:**
  * aided, assisted, coded, collaborated, communicated, executed, exposed to, gained experience, helped, participated, programmed, ran, used, utilized, worked on
  * [Don't use the verb **utilize**. 9/10 times that word will be attached to some disgusting Gordian knot of a sentence that says in 20 words what could be said in 10.](https://scientistseessquirrel.wordpress.com/2019/04/16/for-the-love-of-all-that-is-holy-stop-writing-utilize/)
  * **superfluous/awkward/unnecessarily complex verbs:** amplified, conceptualized, crafted, elevated, employed, engaged, engineered, enhanced, ensured, fostered, headed, honed, innovated, mastered, orchestrated, perfected, pioneered, revolutionized, spearheaded, transformed
  * **frequently misused verbs:** [leverage](https://www.steverrobbins.com/articles/leverage/), [enhance](https://english.stackexchange.com/questions/105465/what-differences-are-there-between-to-enhance-and-to-improve), [utilize](https://scientistseessquirrel.wordpress.com/2019/04/23/limited-use-cases-for-utilize/)

---

#### Each bullet point should follow STAR, XYZ, or CAR

**STAR:** **S**ituation, **T**ask, **A**ction, and **R**esults

* <https://www.levels.fyi/blog/applying-star-method-resumes.html>
* <https://resumegenius.com/blog/resume-help/star-method-resume>

**XYZ:** Accomplished **[X]** as measured by **[Y]**, by doing **[Z]**

* <https://www.inc.com/bill-murphy-jr/google-recruiters-say-these-5-resume-tips-including-x-y-z-formula-will-improve-your-odds-of-getting-hired-at-google.html>

#### [Ultimate Guide to Writing Software Engineer Bullet Points](https://archive.ph/Xmdqt)

---

#### Having trouble coming up with content for your bullet points? Ask yourself the following questions:

**What did I do?** 

* Did I solve a problem?
* Did I work on a team or work independently?
* How many people were on my team?

**How did I do it?**  

* Why did I do it / why did I do it that specific way?
* Did I use any tools or resources to help me? This could be software like MATLAB or SolidWorks, certain reference material like ASME 14.5, etc.
* Did I do any testing to validate my design choices? How did that testing impact my final design?

**What were the results of my actions?**   

* Did I deliver my project on time or under budget?
* Was I successful with the design/solution/project? Did it actually work the way I wanted it to?
* What went wrong? Did I learn anything from the experience?

---

#### Got Writer's Block from Looking at STAR/CAR/XYZ?

Here’s a fun exercise I learned from my last supervisor. At the start of every project, you and/or a task lead likely sat down and established the goals you had to meet, right? Ideally, these goals were set up in such a way that you could meet them and solid enough that you had to exert effort to make them happen.

Now that it’s time to write it up on your resume, start thinking back to what you did back then. Obviously, you met this goal - bold of you to put a failure on your resume - so look at how you met the goal. Did you deliver all five widgets in the agreed-upon six months? Did they have the ability to complete operations X, Y, and Z? Good!

Here’s the fun part. Did you exceed the goals in any way? If you did, how so? Did your delivered widgets reach the customer in half the time and do twice the operations in half the time? If you can flesh this out, you're in a good place.

Don't worry about writing at length. This is a planning exercise. Just get it all on paper and pick your brain until you think everything is on there. Even if you’re not 100% sure about exceeding a goal, just write it down.

When you're finally satisfied, start paring it down to meet space & content requirements.

---

#### Why Integration Matters

Don't throw a parts list at the reader. It matters less what specific components and subcomponents you used and more how you integrated all this into whatever your project was aiming to accomplish.

I'm not saying "yeah I made a machine that did task X" is sufficient, but just telling the reader your widget uses a Raspberry Pi and a stepper motor to do task X isn't helpful either.

How did your software interface with the stepper motors to complete task X to a desired level of precision? That's the kind of stuff that stands out and shows the reader your technical abilities.

---

#### Handling Sensitive Content (or u/graytotoro’s Suggestions on How to Not Get Fired And/Or Sued)

You’ve finally decided to move on from that job working on the X-02S Strike Wyvern on behalf of the Erusean Air and Space Agency. In your time on this project, you supported integration efforts for subsystems enabling this airplane to do things the likes of which would make other nations cower in fear.

But how do you talk about that on your resume without revealing information that would make you persona non grata from a particular industry or the recipient of an expensive-looking letter from a legal firm?

The answer: talk about the technologies behind it without saying the forbidden words. Choose your words very very carefully.

Instead of saying “I developed C++ software for testing LANTIRN display pod software used on the F-14D Tomcat”, consider “I developed C++ software for evaluating aircraft subsystems on [some hardware standard]-based test bench” OR “I created a proof-of-concept integrating COTS whatever items into a data recorder” - you shed just enough light on the subject without resorting to a vague “I did some stuff for these guys”. Of course, it goes without saying that you should still use the STAR criteria to flesh it out as necessary.

For a little less silly example, I once worked at a company that made carbon fiber widgets for airplanes. It was very obviously carbon fiber and even an idiot like me could tell, but we couldn't go around revealing our exact layups and procedures. Saying "a new standard process used to form composite parts, reducing lead times by 33% and (whatever other metrics)" would not be revealing anything too much. If they pry deeper, that's when you can say "no".

\*Not a lawyer (shh) so I can’t help you if you get into a Tom Clancy situation.

\*\*I didn’t actually do this, it’s an example. Sure would be cool though.

---

## Education

* Do **not** include coursework unless the courses are **extremely specialized** or **really cool** like Underwater Autonomous Robotics
* Don't include your high school
* Don't include schools from which you did not receive a degree
* Don't include your start dates, only your graduation date. Don't include a date range
  * If currently a student: **Expected May 2025**
  * If graduated: **May 2021** or simply **2021**
* This section should be in reverse chronological order. i.e. your master's degree goes above your bachelor's degree
* GPA
  * Generally, if your GPA is above 3.75, put it on your resume
  * 2 decimal places is sufficient, 3 is overkill
  * Once you start your first full-time job and your education section is moved to the bottom of your resume, remove your GPA unless it's very impressive
* On your resume, it's **Bachelor ~~'s~~ of Science** and **Master ~~'s~~ of Science**
* Don't include your school location if your school has the location in its name i.e. MIT or UCLA or if its location is commonly known
* Don't include awards/scholarships unless they're extremely impressive, i.e. Rhodes Scholar, Fulbright Scholar
* Include D1/competitive sports

## Skills

shoutout to u/0ffkilter

### Objective

The purpose of the skills section is to highlight in a few words what technical skills you can bring to the job.  Ideally, these match the job description.  They can also include other technical skills that are related, but perhaps not necessarily in the job description.  If you are applying to a job that's in Java, saying you also know C++ can be useful.  This is not a section to spew every buzzword on every technology you've ever touched.  Find a balance between enough skills (to show you can [wear many hats](https://www.merriam-webster.com/dictionary/wear%20many%20hats)) while not showing too many so that the reader makes it seem like none of them are important.  

This section should simply be named **Skills**, not ~~"Technical Skills", "Relevant Skills”, etc~~


#### You Should:

* Include languages you've used thoroughly and could theoretically interview in.
* Include technologies (frameworks, tools, and programs) that you've used previously.
* Repeat things that you use in your bullet points.  If you have Java in your skills, your bullet points in job descriptions should include Java, and vice versa.

#### You Should Not:

* Include soft skills  - don't include things like "teamwork", "leadership", and the like.  Demonstrate via your bullet points and descriptions that you've done these things, not just by listing them out.
* Include skills that are taken for granted and are assumed (typing, Microsoft Word, IDEs, etc - some of these are fine for other types of jobs, but are generally not useful for engineering)
  * Generally speaking, do not include:
    * Code Repository Websites (the skill itself is fine - use "Git" or "SVN", not "GitHub" or "Bitbucket" or "GitLab"
    * Operating Systems
    * IDEs or other word editors (VS Code, LaTeX, vim, etc)

### Formatting:

Your formatting should be easy to read, easy to digest, and convey what's important and what's simply "there".  Each skill should listed should feel important, and not like fluff.

#### You Should:

* Use 3 lines or less, in a single column format.
* Order your skills from most important to least important.
  * Consider whether the ones at the end should even be there
* Separate your skills into relevant categories such as **Software, Mechanical Design, Simulation and Analysis, Manufacturing, Lab Equipment, Languages, Technologies, or Design Tools**

* Use proper formatting:
  * Separate using properly punctuated commas, and not hyphens, dashes, pipes, or anything else.
  * Capitalize each of the skills properly, and if it has a proper name be sure to use that.
    * Solid**W**orks, C**ATIA V**5, LabV**IEW**, [etc..](https://www.reddit.com/r/EngineeringResumes/wiki/typo)
  * Separate similar skills if they are functionally different - 
    * Use "C, C++" not "C/C++".  Each skill should be separate, if necessary.  [see more here](https://www.reddit.com/r/EngineeringResumes/wiki/typo)

#### You Should Not:

* Bold random words or use unnecessary formatting.  The _only_ necessary formatting is if the name of the skill is expressly formatted in a way.
* Use any descriptor when describing your skills.  Do not say "Expert in _ " or "Professional in _".  List the _skill_ only, and use your bullet points to demonstrate your professional abilities.
* Use multiple columns.  One line, one column per group.  Listing skills vertically takes up too much space.  The highlight of your resume is in the words, and your skill bullet points are only here to get the point across and to be a reference of sorts.  


### Should I:

#### Should I include random hobbies and other things?

* No.  You may hear about the stories where the interviewer and interviewee share a hobby or passion project on the side unrelated to the job.  That may work every now and then, and it is _acceptable_ (sometimes) to put these on your resume, but the skills section is not the correct area.  You should include that in a subsection, and only if there is nothing better to put on your resume.  

#### Should I include skills that I'm not super comfortable with, if I'm new to the industry?

* This is a judgement call.  An inexperienced engineer that lists a few skills they've really honed in on can often look better than a new engineer with 10+ skills they've clearly never used in industry.  Find a balance, and try to differentiate what you've used and are experienced with in, and what you've just "touched".

---

## Projects

This section should be named **Projects**, not ~~Academic/Engineering/Notable/Personal/Relevant/Selected/Technical Projects~~

* This section is for personal projects, student design teams, and extracurricular/hobbyist projects, **not** projects from work
* Don't use the word "project" in your project titles, it's redundant
* [Capitalize your project titles correctly](https://capitalizemytitle.com/) <https://capitalizemytitle.com/>
* For personal projects, roles/positions/locations/dates are generally unnecessary. What's more important is including a link to a portfolio page and/or GitHub repo
* There's no need to disclose "Personal Project", "Academic Project", or "Group Project" beside your project title
* Each project should consist of bullet points, ~~not paragraphs~~
* Order projects and bullet points based on relevance to the specific job and general impressiveness. Put your best stuff first and grab the reader's attention!

If you want your projects to stand out, they should be real projects, not mandatory school projects or trivial tutorial projects found online. Something that someone uses to solve a problem. Something that has users (can be just you, as long as you use it often) and is actively maintained and isn't just rotting in a GitHub repo, never to see a PR for the rest of its life. You can always join student clubs like SAE/AIAA competitive teams, and rocketry teams, or even be a mentor for an FRC/FTC team.

## Portfolios

Include links to GitHub profiles and portfolio websites only if they are up-to-date. If your pinned repositories lack READMEs or if your portfolio hasn't been updated in a significant time frame, it's advisable to save space and omit them from your resume. Contrary to common belief, these links are not obligatory, especially when their contents do not contribute meaningful value to your application.

* Only publish projects with good READMEs on GitHub. Aim for each README to have a good summary, screenshots, details on how to run, and **how to test**.
  * Include tests for your project that can be run. Have automated tests such as unit tests or end-to-end tests.
  * Take inspiration from projects with awesome READMEs <https://github.com/matiassingers/awesome-readme>
* [The Portfolio Handbook](https://evaeducation.weebly.com/uploads/1/9/6/9/19692577/portfoliohandbook.pdf) is an excellent guide to creating portfolios. Note that this guide was written for industrial design students
* Don't include full URLs for links
  * ~~<https://www>.~~ github.com/bob
  * ~~<https://www>.~~ portfolio.com

## Bias

* Don't include personal details to your resume that can lead to negative bias during the resume screen
* This includes age/gender/children/nationality/ethnicity/marriage status/religion/political views

---

## Senior Engineers and Above (10+ YoE)

* Consider including a brief summary (<2 sentences)
* Have separate resumes for management and IC positions
* Try not to go over 2 pages
* Mention “soft” achievements on top of the business results
* Mention not only your impact but also your influence
* Make your earlier work experiences more concise
* Move your education section to the bottom of your resume

---

## Career Changers

* Include a brief summary (2 sentences) explaining that you’ve changed careers and your motivation. It’s helpful for recruiters and hiring managers to have the context that they’re reading the resume of someone who has recently changed into software development or another field
* Link to working projects and source code
* Be concise in summarizing past work experience
* Have a short resume. Try to fit on 1 page

---

## Grammar, Punctuation, and Spelling

* Spell out obscure abbreviations in full the first time you use them. The first letter of each word is typically not capitalized (e.g., use "scanning tunneling microscope (STM)" instead of "Scanning Tunneling Microscope (STM)").
* [Tips For Effective Proofreading](https://ualr.edu/writingcenter/tips-for-effective-proofreading/)
* Typos and poor grammar on a resume come across as not paying attention to detail. They can easily cause your resume to be ignored.  
* Do a grammar check, not just a spell check. This includes punctuation: only capitalize [proper nouns](https://www.grammarly.com/blog/proper-nouns/)
* Use free spell checking tools like [Grammarly](http://app.grammarly.com), [Hemingway Editor](http://hemingwayapp.com), [LanguageTool](https://languagetool.org/), and [Quillbot](https://quillbot.com/)
* Ask friends and family to proofread your resume. A fresh set of eyes never hurts.

## u/emnm47's How To Get A Job™ Speech

Networking is EVERYTHING (or at least a skewed amount) now that apps are online, and it's easy to use filters. You must network to have a chance, unless you're in the top 3% of candidates (those people can toss a resume in and get lots of bites). If you continue to throw applications out there without networking, it is highly unlikely you will get picked up. I will get more into networking later BUT here are some steps for How To Get A Job™:

**Step 1:** Evaluate your desperation level

* How much money do you have saved up?
* Do you have any dependents, loans, rent, debts, or food money concerns?
* Should you get a part-time job or file for unemployment while you continue to search?

**Step 2:** Set a timeline.

* For example: "If I haven't accepted a position by Jan 1st, I am changing x y, and z."
* Your timeline will rely on your desperation level. Feel free to break it up into tiers as your desperation increases and the timeline shortens.

**Steps 3-7:** What you can do to improve (aka the x y and z):

* Edit your resume (hey, you’re in the right place!)
* Up your networking game (see below)
* Revamp your LinkedIn profile
* Follow up on previous applications
* Refocus on a different job market, geographic area, or company size if needed

You can't blindly send off 100 applications online and wait to hear back. You have to use your network of friends, family, ex-coworkers, peers, professors, etc. to ask around for openings. While Aunt Lucy might not be an engineer, one of her girlfriends in spin class might be. Actually making contact with someone on “the other side” (engineer, manager, HR, hiring manager, etc.) is huge and will get your name in their head. Follow up after every application. You may feel like you're being annoying, but honestly, people forget, so following up a few times is not a bad thing.

It’s so easy now to just send off a resume to a position. A single opening could have 100 applicants, and maybe the top 10 get interviews and the top 3 get offers. This is great for those with spectacular resumes - you know the type, who interned at SpaceX, built prosthetics for puppies in their spare time, and tutored underprivileged kids in STEM on the weekends, all while getting stellar grades. These few people look amazing on paper and receive interest from all over the board.

Only a few people can draw interest from resumes alone. That’s when you need that name recognition and a willingness to pull your application and take a look at it. If you can get someone to actually look at it, you have a big advantage.

# Svelte5
We are using Svelte 5 instead of svelte 4. Use the @svelte5 docs we've added, but here is some additional help:

#### Overview

Svelte 5 introduces runes, a set of advanced primitives for controlling reactivity. The runes replace certain non-runes features and provide more explicit control over state and effects.

#### $state

- **Purpose:** Declare reactive state.
- **Usage:**

```javascript
<script>let count = $state(0);</script>
```

- **Replaces:** Top-level `let` declarations in non-runes mode.
- **Class Fields:**

```javascript
class Todo {
	done = $state(false);
	text = $state();
	constructor(text) {
		this.text = text;
	}
}
```

- **Deep Reactivity:** Only plain objects and arrays become deeply reactive.

#### $state.raw

- **Purpose:** Declare state that cannot be mutated, only reassigned.
- **Usage:**

```javascript
<script>let numbers = $state.raw([1, 2, 3]);</script>
```

- **Performance:** Improves with large arrays and objects.

#### $state.snapshot

- **Purpose:** Take a static snapshot of $state.
- **Usage:**

```javascript
<script>
	let counter = $state({ count: 0 });

	function onClick() {
		console.log($state.snapshot(counter));
	}
</script>
```

#### $derived

- **Purpose:** Declare derived state.
- **Usage:**

```javascript
<script>let count = $state(0); let doubled = $derived(count * 2);</script>
```

- **Replaces:** Reactive variables computed using `$:` in non-runes mode.

#### $derived.by

- **Purpose:** Create complex derivations with a function.
- **Usage:**

```javascript
<script>
	let numbers = $state([1, 2, 3]); let total = $derived.by(() => numbers.reduce((a, b) => a + b,
	0));
</script>
```

#### $effect

- **Purpose:** Run side-effects when values change.
- **Usage:**

```javascript
<script>
	let size = $state(50);
	let color = $state('#ff3e00');

	$effect(() => {
		const context = canvas.getContext('2d');
		context.clearRect(0, 0, canvas.width, canvas.height);
		context.fillStyle = color;
		context.fillRect(0, 0, size, size);
	});
</script>
```

- **Replacements:** $effect replaces a substantial part of `$: {}` blocks triggering side-effects.

#### $effect.pre

- **Purpose:** Run code before the DOM updates.
- **Usage:**

```javascript
<script>
	$effect.pre(() =>{' '}
	{
		// logic here
	}
	);
</script>
```

- **Replaces:** beforeUpdate.

#### $effect.tracking

- **Purpose:** Check if code is running inside a tracking context.
- **Usage:**

```javascript
<script>console.log('tracking:', $effect.tracking());</script>
```

#### $props

- **Purpose:** Declare component props.
- **Usage:**

```javascript
<script>let {(prop1, prop2)} = $props();</script>
```

- **Replaces:** export let syntax for declaring props.

#### $bindable

- **Purpose:** Declare bindable props.
- **Usage:**

```javascript
<script>let {(bindableProp = $bindable('fallback'))} = $props();</script>
```

#### $inspect

- **Purpose:** Equivalent to `console.log` but re-runs when its argument changes.
- **Usage:**

```javascript
<script>let count = $state(0); $inspect(count);</script>
```

#### $host

- **Purpose:** Retrieve the this reference of the custom element.
- **Usage:**

```javascript
<script>
	function greet(greeting) {
		$host().dispatchEvent(new CustomEvent('greeting', { detail: greeting }));
	}
</script>
```

- **Note:** Only available inside custom element components on the client-side.

#### Overview of snippets in svelte 5

Snippets, along with render tags, help create reusable chunks of markup inside your components, reducing duplication and enhancing maintainability.

#### Snippets Usage

- **Definition:** Use the `#snippet` syntax to define reusable markup sections.
- **Basic Example:**

```javascript
{#snippet figure(image)}
	<figure>
		<img src={image.src} alt={image.caption} width={image.width} height={image.height} />
		<figcaption>{image.caption}</figcaption>
	</figure>
{/snippet}
```

- **Invocation:** Render predefined snippets with `@render`:

```javascript
{@render figure(image)}
```

- **Destructuring Parameters:** Parameters can be destructured for concise usage:

```javascript
{#snippet figure({ src, caption, width, height })}
	<figure>
		<img alt={caption} {src} {width} {height} />
		<figcaption>{caption}</figcaption>
	</figure>
{/snippet}
```

#### Snippet Scope

- **Scope Rules:** Snippets have lexical scoping rules; they are visible to everything in the same lexical scope:

```javascript
<div>
	{#snippet x()}
		{#snippet y()}...{/snippet}

		<!-- valid usage -->
		{@render y()}
	{/snippet}

	<!-- invalid usage -->
	{@render y()}
</div>

<!-- invalid usage -->
{@render x()}
```

- **Recursive References:** Snippets can self-reference or reference other snippets:

```javascript
{#snippet blastoff()}
	<span>🚀</span>
{/snippet}

{#snippet countdown(n)}
	{#if n > 0}
		<span>{n}...</span>
		{@render countdown(n - 1)}
	{:else}
		{@render blastoff()}
	{/if}
{/snippet}

{@render countdown(10)}
```

#### Passing Snippets to Components

- **Direct Passing as Props:**

```javascript
<script>
	import Table from './Table.svelte';
	const fruits = [{ name: 'apples', qty: 5, price: 2 }, ...];
</script>

{#snippet header()}
	<th>fruit</th>
	<th>qty</th>
	<th>price</th>
	<th>total</th>
{/snippet}

{#snippet row(fruit)}
	<td>{fruit.name}</td>
	<td>{fruit.qty}</td>
	<td>{fruit.price}</td>
	<td>{fruit.qty * fruit.price}</td>
{/snippet}

<Table data={fruits} {header} {row} />
```

- **Implicit Binding:**

```html
<table data="{fruits}">
	{#snippet header()}
	<th>fruit</th>
	<th>qty</th>
	<th>price</th>
	<th>total</th>
	{/snippet} {#snippet row(fruit)}
	<td>{fruit.name}</td>
	<td>{fruit.qty}</td>
	<td>{fruit.price}</td>
	<td>{fruit.qty * fruit.price}</td>
	{/snippet}
</table>
```

- **Children Snippet:** Non-snippet content defaults to the `children` snippet:

```html
<table data="{fruits}">
	<th>fruit</th>
	<th>qty</th>
	<th>price</th>
	<th>total</th>
	<!-- additional content -->
</table>

<script>
	let { data, children, row } = $props();
</script>

<table>
	<thead>
		<tr>
			{@render children()}
		</tr>
	</thead>
	<!-- table body -->
</table>
```

- **Avoid Conflicts:** Do not use a prop named `children` if also providing content inside the component.

#### Typing Snippets

- **TypeScript Integration:**

```typescript
<script lang="ts">
	import type { Snippet } from 'svelte';

	let { data, children, row }: {
		data: any[];
		children: Snippet;
		row: Snippet<[any]>;
	} = $props();
</script>
```

- **Generics for Improved Typing:**

```typescript
<script lang="ts" generics="T">
	import type { Snippet } from 'svelte';

	let { data, children, row }: {
		data: T[];
		children: Snippet;
		row: Snippet<[T]>;
	} = $props();
</script>
```

#### Creating Snippets Programmatically

- **Advanced Use:** Create snippets programmatically using `createRawSnippet` where necessary.

#### Snippets and Slots

- **Mixing with Slots:** Slots are deprecated but still work. Snippets provide more flexibility and power.
- **Custom Elements:** Continue using `<slot />` for custom elements as usual.

Sure! Here are the succinct instructions for handling Event Handlers in Svelte 5, tailored for the AI-integrated code editor to help it understand and utilize these features effectively.

---

### Custom Instructions for Svelte 5 Event Handlers in Cursor AI

#### Overview

In Svelte 5, event handlers are treated as properties, simplifying their use and integrating them more closely with the rest of the properties in the component.

#### Basic Event Handlers

- **Declaration:** Use properties to attach event handlers.

```javascript
<script>
	let count = $state(0);
</script>

<button onclick={() => count++}>
	clicks: {count}
</button>
```

- **Shorthand Syntax:**

```javascript
<script>
	let count = $state(0);

	function handleClick() {
		count++;
	}
</script>

<button {handleClick}>
	clicks: {count}
</button>
```

- **Deprecation:** The traditional `on:` directive is deprecated.

#### Component Events

- **Replacing createEventDispatcher:** Components should accept callback props instead of using `createEventDispatcher`.

```javascript
<script>
	import Pump from './Pump.svelte';

	let size = $state(15);
	let burst = $state(false);

	function reset() {
		size = 15;
		burst = false;
	}
</script>

<Pump
	inflate={(power) => { size += power; if (size > 75) burst = true; }}
	deflate={(power) => { if (size > 0) size -= power; }}
/>

{#if burst}
	<button onclick={reset}>new balloon</button>
	<span class="boom">💥</span>
{:else}
	<span class="balloon" style="scale: {0.01 * size}"> 🎈 </span>
{/if}
```

#### Bubbling Events

- **Accept Callback Props:**

```javascript
<script>
	let { onclick, children } = $props();
</script>

<button {onclick}>
	{@render children()}
</button>
```

- **Spreading Props:**

```javascript
<script>
	let { children, ...props } = $props();
</script>

<button {...props}>
	{@render children()}
</button>
```

#### Event Modifiers

- **Avoiding Modifiers:** Modifiers like `|once`, `|preventDefault`, etc., are not supported. Use wrapper functions instead.
- **Example Wrapper Functions:**

```javascript
<script>
	function once(fn) {
		return function (event) {
			if (fn) fn.call(this, event);
			fn = null;
		};
	}

	function preventDefault(fn) {
		return function (event) {
			event.preventDefault();
			fn.call(this, event);
		};
	}
</script>

<button onclick={once(preventDefault(handler))}>...</button>
```

- **Special Modifiers:** For `capture`:

```javascript
<button onclickcapture={...}>...</button>
```

#### Multiple Event Handlers

- **Combining Handlers:** Instead of using multiple handlers, combine them into one.

```javascript
<button
	onclick={(e) => {
		handlerOne(e);
		handlerTwo(e);
	}}
>
	...
</button>
```

### examples old vs new

#### Counter Example

- **Svelte 4 vs. Svelte 5:**

  - **Before:**

  ```html
  <script>
  	let count = 0;
  	$: double = count * 2;
  	$: {
  		if (count > 10) alert('Too high!');
  	}
  </script>

  <button on:click="{()" ="">count++}> {count} / {double}</button>
  ```

  - **After:**

  ```html
  <script>
  	let count = $state(0);
  	let double = $derived(count * 2);
  	$effect(() => {
  		if (count > 10) alert('Too high!');
  	});
  </script>

  <button onclick="{()" ="">count++}> {count} / {double}</button>
  ```

#### Tracking Dependencies

- **Svelte 4 vs. Svelte 5:**

  - **Before:**

  ```html
  <script>
  	let a = 0;
  	let b = 0;
  	$: sum = add(a, b);

  	function add(x, y) {
  		return x + y;
  	}
  </script>

  <button on:click="{()" ="">a++}>a++</button>
  <button on:click="{()" ="">b++}>b++</button>
  <p>{a} + {b} = {sum}</p>
  ```

  - **After:**

  ```html
  <script>
  	let a = $state(0);
  	let b = $state(0);
  	let sum = $derived(add());

  	function add() {
  		return a + b;
  	}
  </script>

  <button onclick="{()" ="">a++}>a++</button>
  <button onclick="{()" ="">b++}>b++</button>
  <p>{a} + {b} = {sum}</p>
  ```

#### Untracking Dependencies

- **Svelte 4 vs. Svelte 5:**

  - **Before:**

  ```html
  <script>
  	let a = 0;
  	let b = 0;
  	$: sum = a + noTrack(b);

  	function noTrack(value) {
  		return value;
  	}
  </script>

  <button on:click="{()" ="">a++}>a++</button>
  <button on:click="{()" ="">b++}>b++</button>
  <p>{a} + {b} = {sum}</p>
  ```

  - **After:**

  ```html
  <script>
  	import { untrack } from 'svelte';

  	let a = $state(0);
  	let b = $state(0);
  	let sum = $derived(add());

  	function add() {
  		return a + untrack(() => b);
  	}
  </script>

  <button onclick="{()" ="">a++}>a++</button>
  <button onclick="{()" ="">b++}>b++</button>
  <p>{a} + {b} = {sum}</p>
  ```

#### Simple Component Props

- **Svelte 5:**

  ```html
  <script>
  	let { count = 0 } = $props();
  </script>

  {count}
  ```

#### Advanced Component Props

- **Svelte 5:**

  ```html
  <script>
  	let { class: classname, ...others } = $props();
  </script>

  <pre class="{classname}">
    {JSON.stringify(others)}
  </pre>
  ```

#### Autoscroll Example

- **Svelte 4 vs. Svelte 5:**

  - **Before:**

  ```html
  <script>
  	import { tick, beforeUpdate } from 'svelte';

  	let theme = 'dark';
  	let messages = [];
  	let viewport;
  	let updatingMessages = false;

  	beforeUpdate(() => {
  		if (updatingMessages) {
  			const autoscroll =
  				viewport && viewport.offsetHeight + viewport.scrollTop > viewport.scrollHeight - 50;
  			if (autoscroll) {
  				tick().then(() => viewport.scrollTo(0, viewport.scrollHeight));
  			}
  		}
  	});

  	function handleKeydown(event) {
  		if (event.key === 'Enter') {
  			const text = event.target.value;
  			if (text) {
  				messages = [...messages, text];
  				updatingMessages = true;
  				event.target.value = '';
  			}
  		}
  	}

  	function toggle() {
  		theme = theme === 'dark' ? 'light' : 'dark';
  	}
  </script>

  <div class:dark="{theme" ="" ="" ="dark" }>
  	<div bind:this="{viewport}">
  		{#each messages as message}
  		<p>{message}</p>
  		{/each}
  	</div>

  	<input on:keydown="{handleKeydown}" />
  	<button on:click="{toggle}">Toggle dark mode</button>
  </div>
  ```

  - **After:**

  ```html
  <script>
  	import { tick } from 'svelte';

  	let theme = $state('dark');
  	let messages = $state([]);
  	let viewport;

  	$effect.pre(() => {
  		messages;
  		const autoscroll =
  			viewport && viewport.offsetHeight + viewport.scrollTop > viewport.scrollHeight - 50;
  		if (autoscroll) {
  			tick().then(() => viewport.scrollTo(0, viewport.scrollHeight));
  		}
  	});

  	function handleKeydown(event) {
  		if (event.key === 'Enter') {
  			const text = event.target.value;
  			if (text) {
  				messages = [...messages, text];
  				event.target.value = '';
  			}
  		}
  	}

  	function toggle() {
  		theme = theme === 'dark' ? 'light' : 'dark';
  	}
  </script>

  <div class:dark="{theme" ="" ="" ="dark" }>
  	<div bind:this="{viewport}">
  		{#each messages as message}
  		<p>{message}</p>
  		{/each}
  	</div>

  	<input onkeydown="{handleKeydown}" />
  	<button onclick="{toggle}">Toggle dark mode</button>
  </div>
  ```

#### Forwarding Events

- **Svelte 5:**

  ```html
  <script>
  	let { ...props } = $props();
  </script>

  <button {...props}>a button</button>
  ```

#### Passing UI Content to a Component

- **Passing content using snippets:**

  ```html
  <!-- consumer -->
  <script>
  	import Button from './Button.svelte';
  </script>

  <button>{#snippet children(prop)} click {prop} {/snippet}</button>

  <!-- provider (Button.svelte) -->
  <script>
  	let { children } = $props();
  </script>

  <button>{@render children("some value")}</button>
  ```

I'm also using sveltekit 2 which also has some changes I'd like you to keep in mind

### Redirect and Error Handling

In SvelteKit 2, it is no longer necessary to throw the results of `error(...)` and `redirect(...)`. Simply calling them is sufficient.

**SvelteKit 1:**

```javascript
import { error } from '@sveltejs/kit';

function load() {
	throw error(500, 'something went wrong');
}
```

**SvelteKit 2:**

```javascript
import { error } from '@sveltejs/kit';

function load() {
	error(500, 'something went wrong');
}
```

**Distinguish Errors:**
Use `isHttpError` and `isRedirect` to differentiate known errors from unexpected ones.

```javascript
import { isHttpError, isRedirect } from '@sveltejs/kit';

try {
	// some code
} catch (err) {
	if (isHttpError(err) || isRedirect(err)) {
		// handle error
	}
}
```

### Cookie Path Requirement

Cookies now require a specified path when set, deleted, or serialized.

**SvelteKit 1:**

```javascript
export function load({ cookies }) {
	cookies.set(name, value);
	return { response };
}
```

**SvelteKit 2:**

```javascript
export function load({ cookies }) {
	cookies.set(name, value, { path: '/' });
	return { response };
}
```

### Top-Level Promise Handling

Promises in `load` functions are no longer awaited automatically.

**Single Promise:**

**SvelteKit 1:**

```javascript
export function load({ fetch }) {
    return {
        response: fetch(...).then(r => r.json())
    };
}
```

**SvelteKit 2:**

```javascript
export async function load({ fetch }) {
    const response = await fetch(...).then(r => r.json());
    return { response };
}
```

**Multiple Promises:**

**SvelteKit 1:**

```javascript
export function load({ fetch }) {
    return {
        a: fetch(...).then(r => r.json()),
        b: fetch(...).then(r => r.json())
    };
}
```

**SvelteKit 2:**

```javascript
export async function load({ fetch }) {
    const [a, b] = await Promise.all([
        fetch(...).then(r => r.json()),
        fetch(...).then(r => r.json())
    ]);
    return { a, b };
}
```

### `goto` Changes

`goto(...)` no longer accepts external URLs. Use `window.location.href = url` for external navigation.

### Relative Paths Default

Paths are now relative by default, ensuring portability across different environments. The `paths.relative` config option manages this behavior.

### Deprecated Settings and Functions

- **Server Fetches** are no longer trackable.
- **`preloadCode` Arguments:** Must be prefixed with the base path.
- **`resolvePath` Replacement:** Use `resolveRoute` instead.

```javascript
import { resolveRoute } from '$app/paths';

const path = resolveRoute('/blog/[slug]', { slug: 'hello' });
```

### Improved Error Handling

Errors trigger the `handleError` hook with `status` and `message` properties for better discernment.

### Dynamic Environment Variables

Dynamic environment variables cannot be used during prerendering. Use static modules instead.

### `use:enhance` Callback Changes

The properties `form` and `data` have been removed from `use:enhance` callbacks, replaced by `formElement` and `formData`.

### Forms with File Inputs

Forms containing `<input type="file">` must use `enctype="multipart/form-data"`.

With these adjusted guidelines, your AI can now generate SvelteKit 2 code accurately while considering the migration changes.

- Organize code into functions and modules for clarity and reusability.
- Follow PEP 8 style guidelines for Python code.

JAX Best Practices

- Leverage JAX's functional API for numerical computations.
  - Use `jax.numpy` instead of standard NumPy to ensure compatibility.
- Utilize automatic differentiation with `jax.grad` and `jax.value_and_grad`.
  - Write functions suitable for differentiation (i.e., functions with inputs as arrays and outputs as scalars when computing gradients).
- Apply `jax.jit` for just-in-time compilation to optimize performance.
  - Ensure functions are compatible with JIT (e.g., avoid Python side-effects and unsupported operations).
- Use `jax.vmap` for vectorizing functions over batch dimensions.
  - Replace explicit loops with `vmap` for operations over arrays.
- Avoid in-place mutations; JAX arrays are immutable.
  - Refrain from operations that modify arrays in place.
- Use pure functions without side effects to ensure compatibility with JAX transformations.

Optimization and Performance

- Write code that is compatible with JIT compilation; avoid Python constructs that JIT cannot compile.
  - Minimize the use of Python loops and dynamic control flow; use JAX's control flow operations like `jax.lax.scan`, `jax.lax.cond`, and `jax.lax.fori_loop`.
- Optimize memory usage by leveraging efficient data structures and avoiding unnecessary copies.
- Use appropriate data types (e.g., `float32`) to optimize performance and memory usage.
- Profile code to identify bottlenecks and optimize accordingly.

Error Handling and Validation

- Validate input shapes and data types before computations.
  - Use assertions or raise exceptions for invalid inputs.
- Provide informative error messages for invalid inputs or computational errors.
- Handle exceptions gracefully to prevent crashes during execution.

Testing and Debugging

- Write unit tests for functions using testing frameworks like `pytest`.
  - Ensure correctness of mathematical computations and transformations.
- Use `jax.debug.print` for debugging JIT-compiled functions.
- Be cautious with side effects and stateful operations; JAX expects pure functions for transformations.

Documentation

- Include docstrings for functions and modules following PEP 257 conventions.
  - Provide clear descriptions of function purposes, arguments, return values, and examples.
- Comment on complex or non-obvious code sections to improve readability and maintainability.

Key Conventions

- Naming Conventions
  - Use `snake_case` for variable and function names.
  - Use `UPPERCASE` for constants.
- Function Design
  - Keep functions small and focused on a single task.
  - Avoid global variables; pass parameters explicitly.
- File Structure
  - Organize code into modules and packages logically.
  - Separate utility functions, core algorithms, and application code.

JAX Transformations

- Pure Functions
  - Ensure functions are free of side effects for compatibility with `jit`, `grad`, `vmap`, etc.
- Control Flow
  - Use JAX's control flow operations (`jax.lax.cond`, `jax.lax.scan`) instead of Python control flow in JIT-compiled functions.
- Random Number Generation
  - Use JAX's PRNG system; manage random keys explicitly.
- Parallelism
  - Utilize `jax.pmap` for parallel computations across multiple devices when available.

Performance Tips

- Benchmarking
  - Use tools like `timeit` and JAX's built-in benchmarking utilities.
- Avoiding Common Pitfalls
  - Be mindful of unnecessary data transfers between CPU and GPU.
  - Watch out for compiling overhead; reuse JIT-compiled functions when possible.

Best Practices

- Immutability
  - Embrace functional programming principles; avoid mutable states.
- Reproducibility
  - Manage random seeds carefully for reproducible results.
- Version Control
  - Keep track of library versions (`jax`, `jaxlib`, etc.) to ensure compatibility.
