| /** |
| * 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 }] |
