What I loved about this writeup was the way I could review both by comparing two languages in which I have a moderate understanding. The comparison of imports was very engaging to my brain.
I really feel like I could accelerate learning a new language if the tutorial was written by comparing that language to another language I already know. Partially I just think that would keep my interest. I'm never excited when I start learning a new language and read the description of how to import a module in that new language; my brain would say "doh, I'll review this when I actually start writing code, let me zone out here..." I feel like most language tutorials feel obligated to cover this minutiae and there is always a lot to review when you are writing a tutorial. People would probably get upset if you skipped that stuff, but for me as a reader, I really prefer this approach here.
