слава богу нейросети, что исправила ошибки написанные моими клешнями

Seems that this solution can't be used like a common solution, see tests here http://stackoverflow.com/a/34466248/3429127.
That means that you should avoid usage of ">" and "<" in comparator.

Just want to notice that JS native sort method affects on initial array.
If we want that list argument stays the same we need to make a copy of it inside the function (e. g. using slice()).

nice, I missed information about two dimensional space.

I saw it in a few different kata's solutions. I had the same question.. Correct one is to use substraction.

Came here to ask the same question.
This returns a boolean, which I would guess complies only with returning the 1 or the 0?
How exactly does this solution work?

好机智！

actually you can group all the empty functions into one line. That's what I did :p
