/**
 * Performs a deep comparison between each element in `collection` and the
 * source object, returning the first element that has equivalent property
 * values.
 *
 * **Note:** This method supports comparing arrays, booleans, `Date` objects,
 * numbers, `Object` objects, regexes, and strings. Objects are compared by
 * their own, not inherited, enumerable properties. For comparing a single
 * own or inherited property value see `_.matchesProperty`.
 *
 * @static
 * @memberOf _
 * @category Collection
 * @param {Array|Object|string} collection The collection to search.
 * @param {Object} source The object of property values to match.
 * @returns {*} Returns the matched element, else `undefined`.
 * @example
 *
 * var users = [
 *   { 'user': 'barney', 'age': 36, 'active': true },
 *   { 'user': 'fred',   'age': 40, 'active': false }
 * ];
 *
 * _.result(_.findWhere(users, { 'age': 36, 'active': true }), 'user');
 * // => 'barney'
 *
 * _.result(_.findWhere(users, { 'age': 40, 'active': false }), 'user');
 * // => 'fred'
