javascript

Features and purpose

JavaScript development process and code review. Use when writing JavaScript code, reviewing JavaScript PRs, debugging unexpected behavior, configuring ESLint and Prettier, or setting up testing. Also use when code uses `==` instead of `===`, variables are reassigned frequently, async code isn't awaited, error handling is missing, or module systems are mixed. Essential for ES6+ features, async/await patterns, nullish coalescing, and common JavaScript gotchas.
