I started reading Chapter 2 today. First half of it right now (Before the jobber app began).
I was thinking of mentoring a few folks on Elixir, at least to keep my Elixir claws sharpened since I don’t do that at work. I would say this chapter did a really good job explaining GenServer. And while I just skimmed through the latter half (aka Jobber, a GenServer based job scheduling app that touches DynamicSupervisor and Registry a little) I would be keen on reading it with a pedagogical mindset.
This chapter will be good material if one is equipped with the GenServer section on Elixir Official Guide and Elixir School, at least the first half. The latter half would need a little more intuition around supervisor. But in this book’s defence, it is targetted for folks with some Elixir experience.
I will finish the latter half of Chapter two tonight and will be back with a more detailed review.
