It's actually courseware, so you have to buy the software to see the answers. I just used the site for the tutorial info, not the homework!

A nice supplemental tutorials http://www.tizag.com/javascriptT/

The site I linked below is fraken amazing. You can save iterations of code, you can have multiple people comment on it, tidy it up (does the tab formatting for you), you can see javascript errors via JSLint button, and pick your frameworks (different versions of jQuery, Mootools, YUI, and more)! It's a pretty nice has all this and it shows the result. I've only been playing with this for a little while, but I highly recommend it!http://jsfiddle.net/
