   * @param {Array|Object|string} collection The collection to search.
   * @param {Function|Object|string} [predicate=_.identity] The function invoked
   *  per iteration. If a property name or object is provided it is used to
   *  create a "_.property" or "_.matches" style callback respectively.
   * @param {*} [thisArg] The `this` binding of `predicate`.
   * @returns {*} Returns the matched element, else `undefined`.
   * @example
   *
   * _.findLast([1, 2, 3, 4], function(n) { return n % 2 == 1; });
   * // => 3
