JSDoc: Generate API Documentation from JavaScript Source Code Comments

JSDoc is a markup language used to generate API documentation from JavaScript source code comments. It allows developers to document functions, classes, variables, and more in a standardized format.

What is JSDoc?

JSDoc is an API documentation generator for JavaScript. It allows developers to write documentation comments directly in the source code using a simple markup language. These comments can then be extracted and transformed into HTML API documentation.

Some key features of JSDoc include:

  • Supports documenting JavaScript functions, classes, variables, modules and more
  • Inline documentation using /** */ comment blocks
  • Tag syntax for describing parameters, return values, types, etc
  • Generates an organized, easy to read API documentation website
  • Integrates with code completion and hinting in IDEs like VS Code
  • Customizable through templates
  • Open source and supported by an active community

JSDoc enables more readable and maintainable source code by allowing developers to document right alongside their JavaScript. The documentation can enhance collaboration and code reuse within teams. Setting up JSDoc comments as part of a project's development workflow can greatly improve the quality of its API documentation over time.
