The a-ha moment for me was that functional programming - in most real world applications - is less about "no state" and "no side effects", and more about "properly managed state" and "properly managed side effects". This is one of the things I really like about Elixir/Erlang/OTP - of course your application needs to manage state, but it's well contained and well managed, avoiding a lot of common pitfalls. |
