Depends on the context. I came from a ruby, nodejs, java, gawk background to Erlang (not elixir).
The first question I posed to the Erlang community was exactly that: what are the build tools, what are the unit testing frameworks and how is a project setup.
Not because I didn’t know what these tool/concepts did but because I wanted to know what is the state of the art in Erlang tooling.
I have my sea legs, including the wooden one, but just not yet in Erlang. Why Erlang? Because it’s completely different to everything else!
It's like asking "I'm new to driving, what brand of nitros should I be using"
Nah dude, get your sea legs first
