It offers flexibility, code annotation, and no compilation step, while still allowing for improved code maintainability and understanding. JSDoc can be used to add types to values, objects, arrays, functions, and classes, as well as improve code documentation with features like code authors, example usage, versioning, and helpful links. JSDoc files can be converted into documentation websites or TypeScript declaration files (.d.ts) for integration with TypeScript projects. ## Full article daily.dev links to this article rather than hosting it.
