JavaScript Tutorials Online

The web site http://www.webteacher.com/javascript/ contains a very nice introduction to JavaScript programming for people with no prior programming experience. Even if you have extensive programming experience, this tutorial may prove very informative (it did for me). For now, read only the first three chapters (through the discussion of if-then statements). I also like the interactive learn-by-example teaching style of w3schools.com that I use so freely in lecture.
