damn javascripts and coffeescripts

I wasted like 24 hours on finding suitable coffeescripts tutorial, I
have read almost every of them. But I can't find a usable syntax checker.

I know there's cloud9 or some other plugins.

But once you want to start work on them, they are not as good as they
shall be.

I want to use coffeescript, but I really can't. So I was forced back to
ugly dirty javascripts......
