Documentation Best Practices

  • Start every function with a one-line summary.
  • Document parameters, defaults, optional values, and return types.
  • Use JSDoc tags: `@param`, `@returns`, `@example`, `@throws`, `@deprecated`.
  • Prefer runnable examples over long explanations.
  • Describe async behavior and side effects explicitly.
  • Keep documentation close to the source and generate it consistently.

Well-Documented Open-Source Examples

  • `facebook/react` — component API documentation and source comments
  • `vuejs/core` — strong JSDoc usage and generated API docs
  • `expressjs/express` — practical API docs with examples
  • `lodash/lodash` — detailed function documentation
  • `nodejs/node` — core library documentation and JSDoc
  • `mdn/content` — excellent reference-style documentation
