I believe splice will have to re-index each item following the item(s) removed (or added). If you do a benchmark you'll find that splice doesn't perform all that well removing from the middle of large arrays. If you plan on doing this a lot look into a linked list type structure. Of course there are a lot of data structures you can check out that might fit your needs. Good luck.
