Unfortunately, the Redux setup in this example project is not correct. It's still using the legacy Redux createStore API, using "hand-written" reducer logic with separate action constants, and following an outdated folder structure. Today we teach and recommend using "modern Redux" using our official Redux Toolkit package, the React-Redux hooks API, and a "feature folder" structure with a single "slice" file of Redux logic per feature.

Please see the "Redux Essentials" tutorial and the Redux Style Guide best practices page in our docs for our recommended approaches:
