I could see walking through a debug session document with a junior dev to guide them on how to debug classes of issues better. Or if they’re running into a bug and ask for your help, you could write out the first few debugging steps and let them take it from there. That might be easier to understand than “I’d check service X and see if it’s processing Y like it should or just passing it on to Z”. Having a defined way to explain how to debug an issue could be useful
BEAM is the VM that Erlang runs on. It also supports Elixir and some other lesser known languages
