| * 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' |
