/** | |
* This method is like `_.difference` except that it accepts `comparator` | |
* which is invoked to compare elements of `array` to `values`. The order and | |
* references of result values are determined by the first array. The comparator | |
* is invoked with two arguments: (arrVal, othVal). | |
* | |
* **Note:** Unlike `_.pullAllWith`, this method returns a new array. | |
* | |

* @since 4.0.0 | |
* @category Array | |
* @param {Array} array The array to inspect. | |
* @param {...Array} [values] The values to exclude. | |
* @param {Function} [comparator] The comparator invoked per element. | |
* @returns {Array} Returns the new array of filtered values. | |
* @example | |
* | |
* var objects = [{ 'x': 1, 'y': 2 }, { 'x': 2, 'y': 1 }]; | |
* | |
* _.differenceWith(objects, [{ 'x': 1, 'y': 2 }], _.isEqual); | |
* // => [{ 'x': 2, 'y': 1 }] | |
