Since you already know C, you also know most of JavaScript. The syntax is very similar. I would suggest loading up nodeJS and using it in REPL mode to work your way through the basics. printf = console.log() - without the formating :-( Then starts the hard part of getting a handle on DOM. I recommend David Flanagan's "Rhino book" and Douglas Crockford's articles which you may find at www.crockford.com. In my experience Chrome and Safari developer tools let you explore effectively. Although reading the W3.org standards documents does help clarify difficult points.
