It turns out this is probably not the best way to do it. As per the comments below, be careful using the delete command as it will only set the element to undefined (the length of the array won’t be shortened. I considered deleting this post, but I think it may still be useful in that it helps clarify the difference between slice and delete.
Original post starts here…
If you search for this topic you’ll find that this can be accomplished using the splice function.
MyArray.splice(3, 1);
This was how I was doing it for a while, but I just recently discovered a simpler method.
delete MyArray[3]
Hope this helps,
