Question here - I am a bit confused about the constructor class in the controller method. When initializing the repository inside the constructor, is this just creating a new instance of that repository to be accessed in the API call, since the initial repo inside the controller class is declared as final ? I am a bit confused about the logic behind this set of code that has appeared a few times in this lesson. Thanks!
