      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.

     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 }]
