I recently bought the course and love it: opinionated, and filled with wisdom and design notes. Going through it, there are just a few things that I’m a little unsure of. Caveat, I’m only 38% of the way through it:
- He makes changes to code first, and gets the tests passing again afterwards. I believe, though, that this takes away some of the tests’ strength, as opposed to first changing the tests, and then the code.
- I think that an implicit state machine is created, and to understand it, one must read the whole code. A small improvement would be to create “constants” for the various state symbols, to allow the compiler to catch misspellings.
- The function naming confuses me every time I come back to the code. E.g.,
tally/1. Maybe I’m used to Ruby, where we try to signal whether it’s a function or procedure, and what the return value is. I’d expect (depending on what it actually does) something likecompute_tally,tally_for(game:), etc. Likewise,score_guess(). - So far, there are no “keyword parameters” (not sure what these are called in Elixir. This also makes it harder for me to understand function inputs. And then, I find that I often have to read through a function or two to determine one’s output. It’s very possible I’m not approaching Elixir the right way.
- He doesn’t use the
{ :ok, ... }&{ :error, ... }convention and so more functions are impure than I would personally make.
Overall, though, a very valuable course.

I can personally attest to Dave’s talent as a teacher - he has a really unique perspective and problem solving approach. I’d highly recommend the course!
I was lucky enough to take his university course and have been active in the elixir community since!

” about Elixir presented in the course is still relevant today? I guess most of it should be still valid, but as I am starting now I do not know how things have changed in four years

The only drawbacks from this course, is that, it teaches GenServer in a very unconventional fashion. Albeit that, it’s a very good course!
