| 4 | * This method is like `_.uniq` except that it accepts `comparator` which |
| 5 | * is invoked to compare elements of `array`. The order of result values is |
| 6 | * determined by the order they occur in the array.The comparator is invoked |
| 7 | * with two arguments: (arrVal, othVal). |

| 13 | * @param {Array} array The array to inspect. |
| 14 | * @param {Function} [comparator] The comparator invoked per element. |
| 15 | * @returns {Array} Returns the new duplicate free array. |
