Books (or rather, eBooks, really) are how I learned about programming to begin with. So I'd say I prefer them to an extent, but if you really desire interactability, online sites are definitely the way to go. I tend to retain more gleaning from a book.

Videos are quite good since you easily follow what is happening

While learning something new, I'd prefer to have some kind of guide, so that I understand the basics properly. Later it's definitely the vast ocean of Internet.

20 years ago I'd have still said books are better, but today I prefer websites -- or even pdf's of books -- over actual print for one simple reason.

SEARCH. Good old ^F.

It's also part of why I dislike videos for learning, you can't search them and they're hard to refer back to. Part of why when people refer me to a video (which I find utterly useless in most cases for learning) the first words out of my mouth are "Do you have a transcript?"

I don't read many books. In general, I prefer to look up the specific things I'm stuck at or curious about. Or read the beginner guide / walkthrough / tour of whatever language or library I'm learning.

But coincidentally I did buy Types and Programming Languages yesterday. For getting a good overview of a new field, I think books may be a good way. It'd be only the second book this year.

Books are good, but the best books for me are the ones that guide you through hands-on coding exercises; and online learning systems are a better way to do that.

What I'm really saying is this will remain a personal question with no right and wrong answer. Some people learn best from books, others from tutorials, others from pairing. Most important thing is to find your learning style.
