I came here to post just this. While I like CS, JS isn't this horrid beast people keep making it out to be; often the solutions can be incredibly simple, it's just a matter of thinking about it.

This can be written like this too: keydown_action_map = 37: 'pan_left' 38: 'pan_up' 39: 'pan_right' 40: 'pan_down' 189: 'zoom_out' 187: 'zoom_in' document.addEvent 'keydown', (event) -> action = keydown_action_map[event.keyCode] game_pieces.each game_piece[action], game_piece If you can write terse code in JS you can write it even more terse way in CS.

  Where "more terse" means "removing a useful keyword and replacing parens by spaces". Not exactly impressive (and coffeescript's symbolless maps read horribly badly, imo).

    Which keyword is useful? Var? CS will put it back at compile time, don't worry. And it will do it in more consistent manner than many coders will manually. I have no problems with symbolless maps, and CS will save your ass from being bitten by IE because of stray comma.
