Writing an action
The first building block of state management is that we will write our actions. When writing actions, we have several rules we can follow so that we have good actions in our application:
- Upfront: Writing actions should always come first before developing the features. This gives us an overview of what should be implemented in the application.

- Descriptive: Always provide meaningful information using type metadata. This helps debug the state.
