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.
