How the Redux Flow Works
The diagram uses numbered steps and clear labels to break down the process. Here’s a quick guide to what each step means:
Step ① & ②: Triggering an Action: The React Component (UI) uses dispatch to send an action object (with a type and payload) to the Redux store.
Step ③ & ④: Updating the State: The Reducer function receives the action and the current state, then computes a new state. The Store then saves this new state as the single source of truth.
Step ⑤ & ⑥: Reacting to Changes: Components subscribe to the store. When the state updates, the subscribed components automatically re-render with the fresh data, which you can see in the useSelector hook.
