Treehouse, Codecademy, and Coursera are great tools to teach fundamentals. Books can be good. There are screencasts that can be helpful as well.

Disclosure: I work at Code Fellows.

I agree with you. I suggested these sites to a friend of mine and after then he really got into javascript and ruby. After learning the fundamentals, books are more understandable and more usable lets say.
