remove array

[code]
Useful DO
Actually, what I mostly need is: remove a certain value from an array.
I.e. I have some list of visible IDs and I want to remove one because it’s not visible anymore. So just extend the above example a bit.

>>> var visibleIds = [4,5,6];
>>> var idx = visibleIds.indexOf(5); // Find the index
>>> if(idx!=-1) visibleIds.splice(idx, 1); // Remove it if really found!
[5]
>>> visibleIds
[4, 6]
[/code]
