I sometimes find it hard to get to sleep at night ... :-)
I am an old guy, and I LIKE reading books.
Also I am a 'bouncer'. I understand something at a high level, then want to do the detail to se if it works, then I want to integrate that into my high-level understanding, then extend.
I find I am more effective at learning when I have the materials to support all the ways I learn. Good books fulfil a role for me.
I will install and 'fool around with' webpack, but a really good book would support me learning faster.
Also, I am happy to take a book to 'the can' (no, not the bus:-), but it feels downright weird taking a laptop ;-)
