For most programming books, the first chapter where they teach you Hello, World is mostly about learning how to install the tooling. Then it goes back to explain variables, conditional,... They rarely throws you into code if you're a beginner.

I mean, I didn't need to learn those things, they were just in whatever web GUI I originally learned on; all I knew was that I could ignore it for now, a la the topic. Should the UI have masked that from me until I was ready? I suppose so, but even then I was doing things in an IDE not really knowing what those things were for until much later.
