A nice approach on JavaScript

Just discovered a site where you can learn about JavaScript, with a nice design and cool exercises. In www.codeacademy.com, you can learn the basics on this programming language. There are 4 courses, with several exercises in each one. It's good even for someone who never programmed before, as you can take some very simple tutorials. Give it a try, as they say on the site "Codecademy is the easiest way to learn how to code. It's interactive, fun, and you can do it with your friends".
Share some other sites similar to this one.

Enjoy :)
