After seeing this solution, i learned that, in contrast to BST in other languages, BST(Set) in javascript can hold its insertion order.
This solution is clean and stable.

I don't like this solution because you are mutating the function argument.

Hi dukies_2000,

Are you interested in having this problem translated into other languages?

This is one of those inmstances where if it had been MySQL I would have gotten it right the first time with SQUARE()...

Apparently, sqlite 3.2.8 doesn't have those functions.

um...this is what I had and it was saying SQRT wasn't a function...wtf..

Nice kata. Thanks :)

Nice Kata, but pleeease correct the spelling of the 'Right' method. It might also be worth considering changing the 'Pop Out' method to something else (unshift?) since 'Pop' tends to mean removing the last item in a lot of other languages. I know it is probably my fault for not reading your comment more carefully, but I was stuck on this one point for ages. (cf. principle of least surprise).

Very enjoyable - thank you :)

It's so nice to complete katas with some semblence of 'reality'. Thank you for this kata, I had a lot of fun with it!
