Oh don’t get me wrong, I didn’t mean you need them. They may be very useful if it’s your kink, but I wouldn’t dare say one should learn about them to write elixir code. I was just pointing out that the abstractions are usable in Elixir, even without typeclasses and friends, because they are just abstractions.
But yeah, far better to learn OTP concepts, and indeed basics of reduce and friends ans recursive functions, than wasting time on abstract algebra (unless it’s your kink).
