* This method is like `_.difference` except that it accepts `comparator`
|
2016-09-17 22:24:52 -07:00
|
|
|
* 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).
