In the $ 5.00 video, which you will not find in the book “the same amount from the textbook,” will cover much more information.
edit:
I did not watch the screens, but if you have programming experience, getting a book (maybe even their book?) Would be what I would recommend instead. Just looking through the topics and the time that I don’t see, I don’t see the screen roller (the two available that I mean), going into this detail.
