I get the feeling that the book only covers a fraction of the language. I keep seeing language constructs the book doesn’t treat.

What are the areas that are missing and what would be the best way to infill them?

Protocols?

(Also curious that there would be so many chapters focused on async instead.)

Protocols are in the last chapter if I remember correctly

Things like core.spec is missing I guess, it came in 1.9

Author says that we shouldn’t concern ourselves with performance concerns initially. I agree. Then he introduces take-while before filter and says the only benefit is performance when you think about the sorting of the data

If I had a choice, I’d 100% not be concerned with performance until it became an apparent issue in a real program being written. Then I’d learn it through hot-spot profiling tools and work on it case by case

I mean you gotta take a different collection depending on whether you want to add to the head or the tail. :man-shrugging::skin-tone-3:

True, with all the usual CS implications of linked list vs array vs hash-map, etc. I’ll only complain if it comes up again and again

After reading the book, lists, sets, vectors, collections and sequences have turned into a bit of a data structure ooze in my mind.
