|  | * This method is like `_.findIndex` except that it iterates over elements | 
|  | * of `collection` from right to left. | 
|  | * | 
|  | * @static | 
|  | * @memberOf _ | 
|  | * @since 2.0.0 | 
|  | * @category Array | 
|  | * @param {Array} array The array to inspect. | 
|  | * @param {Function} [predicate=_.identity] The function invoked per iteration. | 
|  | * @param {number} [fromIndex=array.length-1] The index to search from. | 
|  | * @returns {number} Returns the index of the found element, else `-1`. | 
|  | * @example | 
|  | * | 
|  | * var users = [ | 
|  | *   { 'user': 'barney',  'active': true }, | 
|  | *   { 'user': 'fred',    'active': false }, |

|  | * _.findLastIndex(users, function(o) { return o.user == 'pebbles'; }); |

|  | * _.findLastIndex(users, { 'user': 'barney', 'active': true }); | 
|  | * // => 0 | 
|  | * | 
|  | * // The `_.matchesProperty` iteratee shorthand. | 
|  | * _.findLastIndex(users, ['active', false]); |
