  switch (action.type) {
    case 'INCREMENT':
      return { count: state.count + 1 };
    default:
      return state;
  }
};

// Redux store
const store = createStore(counterReducer);

// React component connected to Redux store
const Counter = ({ count, dispatch }) => (
  <div>
    <p>Count: {count}</p>
    <button onClick={() => dispatch({ type: 'INCREMENT' })}>Increment</button>
  </div>
);

// Connecting React component to Redux store
