What's the typical flow of data like in a React + Redux app?

In a React + Redux application, the data flow follows a specific and structured pattern known as unidirectional data flow. Here’s a detailed step-by-step explanation of this process:

1. User Interaction: The flow begins when a user interacts with the UI of the application, such as clicking a button or submitting a form. This interaction triggers an action creator[2].

2. Action Creators: Action creators are functions that create actions. Actions are plain JavaScript objects that describe what happened. These actions must have a type property that indicates the type of action being performed, and they may optionally have a payload that carries data necessary for the action[2][5].

3. Dispatch Action: The action created by the action creator is then dispatched to the Redux store. Dispatching an action is the process of sending the action to the store to trigger a state change[1][2].

4. Reducers: Once the action reaches the store, the store forwards the action to the root reducer. The root reducer may delegate the action to smaller reducers if the application state is managed by multiple reducers. Reducers are pure functions that take the previous state and the dispatched action, and return a new state. They determine how the state changes in response to actions sent to the store[1][2].

5. Store Updates: After the reducers process the action and return the new state, the Re...
