JSDoc: Return object structure

Question

How can I tell JSDoc about the structure of an object that is returned. I have found the @return {{field1: type, field2: type, ...}} description syntax and trie

Answer 1

A clean solution is to write a class and return that.

/** 
 *  @class Point
 *  @type {Object}
 *  @property {number} x The X-coordinate.
 *  @property {number} y The Y-coordinate.
 */
function Point(x, y) {
  return {
        x: x,
        y: y
    };
}

/**
 * @returns {Point} The location of the event.
 */
var getEventLocation = function(e, type) {
    ...
    return new Point(x, y);
};
