What is the role of the Provider component in Redux?

The Provider component from react-redux is used to inject the Redux store into your React app.

Think of it as a context provider that makes the Redux store available to any nested component that needs to access the state.

Typical usage:

import { Provider } from 'react-redux'; import store from './store'; <Provider store={store}> <App /> </Provider>

Without Provider, your components wouldn't be able to connect to Redux or use hooks like useSelector and useDispatch.

In short:
The Provider makes your entire React app aware of the Redux store, enabling state management across the whole component tree.
