/**

* This method is like `_.findKey` except that it iterates over elements of
* a collection in the opposite order.
*
* @static
* @memberOf _
* @since 2.0.0
* @category Object
* @param {Object} object The object to inspect.
* @param {Function} [predicate=_.identity] The function invoked per iteration.
* @returns {string|undefined} Returns the key of the matched element,
*  else `undefined`.
* @example
*
* var users = {
*   'barney':  { 'age': 36, 'active': true },
*   'fred':    { 'age': 40, 'active': false },
*   'pebbles': { 'age': 1,  'active': true }
* };
*
* _.findLastKey(users, function(o) { return o.age < 40; });
* // => returns 'pebbles' assuming `_.findKey` returns 'barney'
*
* // The `_.matches` iteratee shorthand.
* _.findLastKey(users, { 'age': 36, 'active': true });
* // => 'barney'
*
* // The `_.matchesProperty` iteratee shorthand.
* _.findLastKey(users, ['active', false]);
* // => 'fred'
*
* // The `_.property` iteratee shorthand.
* _.findLastKey(users, 'active');
* // => 'pebbles'
