Guide on utilizing TypeScript interfaces or types in JavaScript functions with vscode and jsdocs

Is there a way to utilize types or interfaces to provide intellisense for entire functions or object literals, rather than just function parameters or inline @type's? For example:

type TFunc = ( x: number ) => boolean;

/**
 * @implements {TFunc}
 */
function isNumber ( x ) {
    return typeof x === 'number';
}

The use of @implements does not seem to work in this case. I am curious if there is an alternative method to achieve this.

Answer №1

In my opinion:

Opt for @type over @implements
