This is your typical article featured on About.com. It's informative and straightforward and is complete with tutorials. The tutorials are divided between "modern" and "classical" ways of coding using JS. The author explains that the modern tutorials emphasize much of the same material emphasized in the classical tutorials; however, the latter instructs users in JS programming methods more conducive to older web browsers like IE4 and Netscape.
This website provides informative, introductory material and tutorials about JS. It's a solid resource to incorporate into a tutorial program. I have also used this site as a resource for learning more about using span tags to manipulate the font appearance in WordPress. I found the material to be accessible.
