code: function uniqWith(array, comparator) {
        comparator = typeof comparator == 'function' ? comparator : undefined$1;
        return (array && array.length) ? baseUniq(array, undefined$1, comparator) : [];
      }
docs: 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).

  var objects = [{ 'x': 1, 'y': 2 }, { 'x': 2, 'y': 1 }, { 'x': 1, 'y': 2 }];
  
  _.uniqWith(objects, _.isEqual);
  // => [{ 'x': 1, 'y': 2 }, { 'x': 2, 'y': 1 }]
