JavaScript documentation look-up

Last modified: 08 October 2021

Required plugin: Javascript and TypeScript

The plugin is bundled with CLion and enabled by default.

CLion shows you reference for standard JavaScript APIs, for symbols from your project and from its dependencies, as well as for symbols defined in external libraries. You can view the documentation for symbols in the Documentation popup, get information on method parameters, and open documentation on external sites if links to them are available.

  • For a project symbol or for a symbol from the project dependencies, CLion generates the documentation from the corresponding JSDoc comment.

  • For a standard JavaScript object or method, CLion shows the corresponding JSDoc comment from the built-in TypeScript definition filesd.ts. These files are bundled with CLion and updated on a regular basis.

  • If no comment is found in the d.ts files, CLion shows a summary from the corresponding MDN article.
