As an Elixir dev for coming up on four (four! Jeez where has the time gone?) years, I’ve yet to really delve into Erlang. I can read the syntax well enough to figure out why my Hackney request is doing odd things with my HTTP headers etc..., but that’s about it. To all Erlangers out there, what advantages/niceties/powers do you have in Erlang that make you reach for the language over Elixir?
Mostly I just like it better. But otherwise in my day-to-day off the top of my head:
Less “magic” (fewer macros that may change semantics, straightforward config handling), focus on declarativeness, no variable re-binding, more powerful test framework (common_test), seamless Dialyzer support, better logging framework for structured logging, simpler/minimal syntax, personal preferences for tooling (until recently, direct support for releases was lacking in Elixir), and force of habit.
