Let's take a moment to talk about what is happening behind the scenes in our Elm application.

We mentioned in part 3 that Elm has a Model - Update - View architecture. We've looked at the View and the Model, so let's turn our attention now to the Update. The best way to get a handle on what the update function will need to do is by taking a look at its type annotation.

So far Elm has been happily inferring the types that we are using in our application, and it will continue to do so. However let's take a moment to look at how we can make it more obvious to others who might read our code what types we are expecting.
