Overview

JSDoc provides a standardized way to document JavaScript code with structured comments. AI coding agents excel at generating accurate JSDoc comments by analyzing function signatures, parameter types, return values, and usage patterns.

Agents can automatically add JSDoc blocks to functions, classes, and modules, including @param, @returns, @throws, @example, and @typedef tags. They understand TypeScript types and can generate corresponding JSDoc annotations for JavaScript projects that need documentation without TypeScript.

The generated documentation can be processed by tools like documentation.js or better-docs to create static documentation sites. Teams can enforce JSDoc coverage requirements and use AI agents to fill documentation gaps across the codebase.

Who Is This For?

Generate JSDoc comments for undocumented functions
Add @example tags with usage demonstrations
Create @typedef definitions for complex object shapes
Ensure consistent documentation style across the codebase
