/** |
|
* 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' |
