			* 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'
