Is there anything like: http://nathansjslessons.appspot.com/lesson?id=1000
Something where I can learn and practice javascript? I remember when I was going to start with c++, there was a list of practice exercises for command prompt programs. Anything like that for javascript?
I know the best way to improve is to figure out what I want to do and learn how to do it, but I'm able to do everything I want for the time being, and want to have the ability to do whatever else I want without having to learn it.
