Up and Running with Redux
Section 10
Splice Reducers and Combine Them
Splicing the reducer function into separate reducers each one can manage only a small part of the state and we can combine them again into a root reducer and pass it to the createStore function. - Add a new part in the project for users into the state, action, and reducer to be tested - Make separate reducers for orders and another for users - Combine both reducers into one using combineReducers function and pass it to createStore function
