This seems dangerous...which makes it AWESOME ;)

@passcod I think learning to not be wasteful in the first place isn't premature optimization. document.getElementById is only marginally faster than $('#myId') yes, but by coding more efficiently as you go your app runs better and reduces compute cycles which is definitely important on mobile devices.

@clawfire He didn't say it was the same thing, only to not be afraid of it. People often rely too heavily on jQuery to do mundane tasks.
