| * 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`. |

| * @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' |
