What is JSDoc?
JSDoc parses JavaScript source code to extract information from specially formatted comments, known as JSDoc comments, which use tags like @param, @returns, and @module. It then generates structured API documentation in HTML format, making it easier for developers to understand and use codebases. The tool supports multiple JavaScript module systems including ES 2015 modules, CommonJS, AMD, and Node.js modules, ensuring compatibility with various development environments.
Configuration options allow users to customize output through command-line arguments or configuration files, while plugins extend functionality—such as adding Markdown support. JSDoc includes features for documenting classes, functions, properties, events, and custom types, with tags that specify access levels, deprecation status, and examples. The generated documentation can include tutorials, package details, and README files, providing a complete reference for API consumers.
