Create JSDoc comments
Position the caret before the declaration of the method/function or field to document, type the opening block comment

@param) and return values (
@returns), where applicable. Describe the listed parameters, return values, and so on.

Fix Doc Comment. Then select Fix Doc Comment from the list, and press Enter.
