HTML5 is great. jQuery is cool. Node.JS is awesome.

Base it on a solid, powerful basement of pure JavaScript, and rock the web! ;)

There's a much better version of this tutorial at learn.javascript.ru in Russian. Here it is partially translated and outdated, because I don't really have the time to both continue with the Russian version and do the translation. Besides, my written English is far from perfect. Still I hope you can get something good out of it.
