|
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.
