/**

|
|
* This method is like `_.xor` except that it accepts `comparator` which is
|
||
|
|
* invoked to compare elements of `arrays`. The order of result values is
|
||
|
|
* determined by the order they occur in the arrays. The comparator is invoked
|
||
|
|
* with two arguments: (arrVal, othVal).

|

|
|
* @param {...Array} [arrays] The arrays to inspect.
|

* @param {Function} [comparator] The comparator invoked per element.
|

* @returns {Array} Returns the new array of filtered values.
