Personally, I've cracked very few programming books and I've been building websites since ~2004 back when magazines and books were the best sources for information. Some people learn skills from books well, and some people end up bewildered and confused until they can actually try it out and see how it works. I need to explore to discover and learn.

I did find "Eloquent JavaScript" very helpful, it didn't just get me started on JavaScript but actually introduced that whole computer-sciencey side of programming that I hadn't encountered in my various markup and stylesheet language coding. I never finished Eloquent JavaScript though, it was like a springboard that got me into JavaScript (which is dynamic and has an interactive runtime) and as soon as I could be having a conversation with JavaScript at runtime, from there I continued learning by talking to the REPL and seeing what happened.
