And if you don't need the last element, even faster is to just set
the length of the array. Yes, the elements beyond the length will be
garbage-collected. What you tried first did delete the array
element, but left the length the same, so your array has become
'sparse', which the debugger represents with ellipses.
Since you are the second person in a week to ask this question
(oldben IM-ed me about it), maybe we need to start a Javascript FAQ?

Hi Sarah,
I think you're looking for splice. (I like that name)

so... I thought that to remove an item from an array, I could just
delete it, but that appears not to work as I expected.
This little sample program:
<canvas>
<script>
var a=[0,1,2,3,4,5];
Debug.write(a.length, a);
delete a[5];
Debug.write(a.length, a);
</script>
</canvas
generates this output in the Debugger:
6 [0, 1, 2, 3, 4, 5]
6 [0, 1, 2, 3, 4, ...]
Any one know what I should be doing here to delete an item and
make the
array one item shorter?
Thanks,
Sarah
