The next part is the view function:
view : Model -> Html Msg
view model =
div [] [ text model ]
This is a function that takes a Model argument and returns Html.
If you’re curious, here’s a little explanation about Html Msg. Elm’s Html type takes an argument that indicates the type of messages the user interface will generate. In this example, we pass it Msg to indicate that the Html that our view returns will only ever emit the messages specified by our program’s Msg type. Being specific about this enables the Elm compiler to guarantee that our program handles every message it can produce.
If you’re familiar with a language like TypeScript, Java or Rust that supports generic types, and you’re wondering if Html might be a generic, you’re absolutely right. If you’ve never heard of generic types, don’t sweat it.
