Building a Domain Model in Elixir part 4

The domain model is still developing well. https://github.com/chriseyre2000/pandemic.

The technique of using one line composable functions works well. It also makes the code really readable.

I was surprised how easy it was to enable the “quiet night” card. This can be used at any time and will prevent the next infect city phase from doing anything. It was simple to add a new property to the model, set and unset it. I had expected to have had to build this into the UI (which does not exist yet).
