Where could I find a good -- free or not too expensive -- online JS course for intermediate students? I did the beginners course on the W3 Schools website, plus the DHTML 'course', and passed the test with good grades, but cannot find a good sequel. I know there are some sticky threads on JS resources, but they contain such a lot of links and book titles that I still don't know which to continue with. (A good book recommendation will do as well.)
It is important that it picks up where the W3 Schools course left us, and that it is more or less a real course.
Thanks in advance.
