    Angular 1.x Redux: Handle State Mutations with Reducers

    In this lesson, we are are going to learn how to abstract out state mutations into a reducer. In our current Eggly application, all of the state and business logic for our categories is handled within the categories model. We are going to refactor our code to entirely eliminate the need for our categories model by building out a couple of reducers and seeing how we can interact with them directly. The key thing to notice as we build out our reducers is that a reducer itself is completely stateless because it receives current state every single time it needs to calculate and return the new state. With a clearly defined contract of inputs and outputs, this makes testing reducers really easy which is one of the huge benefits of using this approach.
