Question 1

What is JSDoc?

Accepted Answer

JSDoc is a markup language used to annotate JavaScript source files. With JSDoc comments you can describe function parameters, return values, types and more, which IDEs like VS Code use for inline documentation, autocomplete and TypeScript-style type checking.

Question 2

How does the JSDoc generator detect types?

Accepted Answer

The generator parses your function signature to find parameter names, then inspects default values, TypeScript-style annotations and JSDoc hints already in the source. Where no type can be inferred it falls back to {*} (any). You can also override each type manually in the output.

Question 3

Does the JSDoc generator support arrow functions and async?

Accepted Answer

Yes. Regular functions, arrow functions, generator functions, async functions and class methods are all supported. Async functions automatically get an @returns {Promise<...>} tag.

Question 4

Is this JSDoc generator free and private?

Accepted Answer

Yes. It is 100% free, requires no signup, and runs entirely in your browser. Your JavaScript code never leaves your device.
