In this chapter, we learned that the state in a Redux store is stored in a single place, is read-only, and is changed with a pure function called a reducer. Our components don't talk directly to the reducer; instead, they dispatch functions called action creators, which create objects called actions that describe the change to the reducer.

Redux Thunk was used to allow the store to work with asynchronous actions, which are crucial for an app that uses web services. We told Redux to use Redux Thunk in the Redux createStore function. React components are connected to the store with a connect function from React Redux, as well as a Provider component at the root of the component tree.

There are lots of bits and pieces to get our heads around when implementing Redux within a React app. It does shine in scenarios where the state management is complex because Redux forces...
