/** |
|
* 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. |
|

* @memberOf _ |
|
* @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 }] |
