| 8 | * This method is like `_.difference` except that it accepts `comparator` |
| 9 | * which is invoked to compare elements of `array` to `values`. The order and |
| 10 | * references of result values are determined by the first array. The comparator |
| 11 | * is invoked with two arguments: (arrVal, othVal). |
| 12 | * |
| 13 | * **Note:** Unlike `_.pullAllWith`, this method returns a new array. |
| 14 | * |

| 17 | * @since 4.0.0 |
| 18 | * @category Array |
| 19 | * @param {Array} array The array to inspect. |
| 20 | * @param {...Array} [values] The values to exclude. |
| 21 | * @param {Function} [comparator] The comparator invoked per element. |
| 22 | * @returns {Array} Returns the new array of filtered values. |
| 23 | * @example |
| 24 | * |
| 25 | * var objects = [{ 'x': 1, 'y': 2 }, { 'x': 2, 'y': 1 }]; |
| 26 | * |
| 27 | * _.differenceWith(objects, [{ 'x': 1, 'y': 2 }], _.isEqual); |
| 28 | * // => [{ 'x': 2, 'y': 1 }] |
