Hot 18 game (modified Blackjack) in JavaScript

Question

I've just completed my first JavaScript game. I strongly welcome any advice/opinions/insults on how crappy or good my game is.

Do you notice anything that is poorly done?

Is there anything that I can write better/shorter?

Here is a link where you can change the code/test the game/etc. http://labs.codecademy.com/Bnov#:workspace

function shuffle(deck) {
    for (var i = deck.length - 1; i > 0; i--) {
         var j = Math.floor(Math.random() * (i + 1));
         var temp = deck[i]; deck[i] = deck[j]; deck[j] = temp; } return deck; }

Answer 1

My remarks about the Ruby version of your code also apply to your JavaScript port.

For example hitOrStay() should not recurse, because you're just using it as a goto.

The players' hands should be stored in an array so that you don't have to write special cases for one, two, or three players.
