About JSDoc.fyi
An independently maintained reference for JSDoc.
JSDoc.fyi is an independently produced reference for JSDoc — the markup language used to annotate and document JavaScript code (partially supported by TypeScript) and its documentation generator. It exists to make JSDoc more approachable, with cleaner navigation, consistent examples, and a single place to look up any tag, configuration option, or guide.
This site covers JSDoc 4.0.4, the current stable release as of May 2026. TypeScript support annotations are documented against TypeScript 5.8.
