You would use splice to remove an item. But if I was going to do this,
then I would use a hash and then delete the item and not do the searching
through the array. If you only have 5 items, okay, but 10000 then you have to
search at least 5000 entires ( on avg ) to get your item. But if name is the
key into the hash, then one action to delete the name.
Wags ;)
