This is really minor, but I think the JavaScript Elyse's Enchantments exercise should rename the function removeItemAtBottom → removeItemFromBottom. This makes it consistent with the comment:
That is an important question. It has two obvious answers, each with drawbacks:
Simply change the solution’s requirement by renaming. Legacy solutions all break. Considering that this is an entry-level exercise for a high volume track this should probably be avoided.
Change the name but let the tests accept either the old or the new name. This is a maintenance headache and does not enforce use of the new name.
So considering how minor this issue is it may make sense to just leave it as is.
