Q. What does this code ..for (; i --> 0 ;) {.. means?
A. This is fancy way to write reverse loop, which is arguably looks cleaner compared with classic version of it ..for(var i = array.length; i > 0; i--). In fact construction --> is combination of two operators > and --, so every step i get compared if it is still more than zero and decremented by one afteword.
