/**
 * This method is like `_.find` except that it iterates over elements

 * @static
 * @memberOf _
 * @category Collections
 * @param {Array|Object|string} collection The collection to iterate over.
 * @param {Function|Object|string} [callback=identity] The function called
 *  per iteration. If a property name or object is provided it will be used
 *  to create a "_.pluck" or "_.where" style callback, respectively.
 * @param {*} [thisArg] The `this` binding of `callback`.
 * @returns {*} Returns the found element, else `undefined`.
 * @example
 *
 * _.findLast([1, 2, 3, 4], function(num) {
 *   return num % 2 == 1;
 * });
 * // => 3
