You’ve probably been using books since the first years at the school. You got used to learning from them. It doesn’t matter what you want to learn – physics, cooking, sports, photography – you always take a book. It’s the same with learning how to write code. You can find many programming books in your favorite bookstore and you probably spend tens of hours on selecting the right one.
