We’re talking about not depending on keeping state receiving different mutations. So if you need to keep the state in Elixir, how can it be done? Well, GenServer does, but we’ll get there. Goal We’ll create a stateful process and refactor it until gets the GenServer implementation, in this way you can learn how the state works and how GenServer encapsulates it.
