/**

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

* @param {Array} array The array to inspect.
