That's some great advice.

When you say "don't overwrite", di you mean to start from scratch every chapter? I can imagine this would work for me: repetition is key. But also to get frustratingly boring after a few chapters.

I'll just treat is as any trunk based git repo. Commit significant progress, several times per hour. Then rebase to "summarize" my learnings into a history. I'll commit them to a public repo and treat as if that annoying colleague is going to review. Not that anyone will ever read them. I probably won't myself. But the art of rebasing, amending and pulling apart helps me with what would have been the perfect eLearning history.

No, I just meant save every exercise as a file, like chpt1ex1.js, chpt1ex2.js, &c. A lot of consecutive exercises are just variations on the previous exercise, helping you build your knowledge, but that makes it tempting to overwrite the previous exercise or never save the file. Then you don't have anything to review with after working hard on the book.
