Issue Description

While following the example for using useReducer, there's a Messenger component that uses ContactList, Chat, and a contacts array.

However, the definitions for ContactList, Chat, and contacts are missing from the documentation. This makes it hard to complete the exercise or understand how the example works without looking at the provided solution.

Suggested fix

Add code snippets or links to the necessary components (ContactList, Chat) and data (contacts) directly above or below the Messenger example.
