96: Reviewing Elixir with José Valim - Part 4

1 hour 18 minutes

José Valim returns for part 4 in our 5 part series as we count down to the 10 year anniversary of the Elixir project we know and love! In Part 4, we talk through the Elixir releases of 1.10, 1.11, and 1.12. We go deeper on the philosophy of “explicit vs implicit” and how that informs many design decisions about the language. We learn about how Elixir and Erlang loggers were unified, how matching on map keys in guards enabled receives block enhancements, how common date sorting bugs were solved with Enum.sort improvements (that you should really listen to), the improvements to application config, how exceptions work in Erlang and Elixir and much more! A packed episode!
