Challenge

The code is getting messy. In this challenge, you will refactor it.

Open the challenge

Task 1

Place the datastore and every CRUD operation inside the Repository layer.

Task 2

• Place business and decision-making logic inside the Service layer.
• Make the Service layer the middleman. Because the Service layer handles the business logic, it should make calls to the Repository.

Task 3

Make sure the controller's only concern is managing the model and presenting the view.

Task 4

Run your code to make sure everything still works.

Good Luck!
