That's a really interesting way of reading a programming book. I think one thing on the back of my mind w/my reading style is I want to know as much about the language at any given time so that if I wanted to spin up quick code to do something I don't have to research for it.
I also have this question in the background, if i was at an interview and I had to use this language, am I fluent enough to get around w/access to search things?
I'm going to download mind map and try your way of learning things, I may like it more. It seems to be quicker.
