Idiomatic JavaScript patterns and conventions for maintainable code. Use when writing or refactoring JavaScript following idiomatic patterns and conventions.

JavaScript Best Practices

Priority: P1 (OPERATIONAL)

Implementation Guidelines

  • Naming: camelCase (vars/funcs), PascalCase (classes), UPPER_SNAKE (constants).
  • Errors: Throw Error objects only. Handle all async errors.
  • Comments: JSDoc for APIs. Explain "why" not "what".
  • Files: One entity per file. index.js for exports.
  • Modules: Named exports only. Order: Ext -> Int -> Rel.

Anti-Patterns

  • No Globals: Encapsulate state.
  • No Magic Numbers: Use const.
  • No Nesting: Guard clauses/early returns.
  • No Defaults: Use named exports.
  • No Side Effects: Keep functions pure.

Code & Reference

See references/REFERENCE.md for constants, custom errors, async patterns, and module structure examples.
