| * This method is like `_.findKey` except that it iterates over elements of |
| * a collection in the opposite order. |
| * |
| * If a property name is provided for `predicate` the created `_.property` |
| * style callback returns the property value of the given element. |
| * |
| * If a value is also provided for `thisArg` the created `_.matchesProperty` |
| * style callback returns `true` for elements that have a matching property |
| * value, else `false`. |
| * |
| * If an object is provided for `predicate` the created `_.matches` style |
| * callback returns `true` for elements that have the properties of the given |
| * object, else `false`. |
| * |
| * @static |
| * @memberOf _ |
| * @category Object |
| * @param {Object} object The object to search. |
| * @param {Function|Object|string} [predicate=_.identity] The function invoked |
| * per iteration. |
| * @param {*} [thisArg] The `this` binding of `predicate`. |
| * @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(chr) { |
| * return chr.age < 40; |
| * }); |
| * // => returns `pebbles` assuming `_.findKey` returns `barney` |
| * |
| * // using the `_.matches` callback shorthand |
| * _.findLastKey(users, { 'age': 36, 'active': true }); |
| * // => 'barney' |
| * |
| * // using the `_.matchesProperty` callback shorthand |
| * _.findLastKey(users, 'active', false); |
| * // => 'fred' |
| * |
| * // using the `_.property` callback shorthand |
| * _.findLastKey(users, 'active'); |
| * // => 'pebbles' |
