Comments to the book "Learn You Some Erlang For Great Good" by Fred Hébert, Chapter 4 - Types (or lack thereof). Pattern matching is much easier to achieve in Erlang than in many other languages, but the syntax takes some time to get used to. Instead of if-else or similar conditional branching, in Erlang you simply use functional declarations with a pattern. Learning goals: Understand how Erlang's "crash first" philosophy and always accounting for errors works with dynamical typing to keep things safe. Challenges: See how the lack of static types does not mean that Erlang code is error prone.
