## About

# JavaScript/TypeScript Code Skill

This skill manages JavaScript and TypeScript specific development practices across Node.js, browsers, and edge runtimes.

## When to use this skill
- When writing or maintaining JS/TS applications.
- When dealing with asynchronous programming (Promises, async/await).
- When configuring module systems (ESM vs CommonJS).

## Guidelines
- Prefer TypeScript over vanilla JavaScript for large projects to leverage static typing.
- Always use strict equality (`===`) and avoid loose equality (`==`).
- Avoid mutating state when possible; prefer functional approaches like `map`, `filter`, and `reduce`.
- Use `const` by default, `let` when necessary, and never use `var`.
