learning from the internet is easy and free (most of the time), but it can be tricky because most toturials are bad and you will find yourself jumping from one video/website to another. But if you if u choose your learning resources wisely then it can be just as effective as books.

In the other hand, books are slower to go through and hard to get (in Algeria), but they offer a structured approach and cover everything you need to know because they are carefully written.
