Hey all! I stumbled across this really cool website that uses a game-like interface to teach you Javascript! It's really easy and fun! I'm already about 50% through the Introduction section, but there's several other lessons as well.  Time will tell to see if what I learn here can actually transition to using Javascript in my sites, but for now I feel like I'm learning quickly and having fun.  Check it out!
