| * 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' | |
