How do I implement Redux in my React app?

To implement Redux, first install it using npm: npm install redux react-redux. Then, create a Redux store.

What files do I need to create for Redux?

You'll typically need a store file, actions, reducers, and possibly a middleware file.

Can you show me a simple example of a reducer?

Sure! Here's a basic reducer:

const initialState = { count: 0 };

const counterReducer = (state = initialState, action) => {
  switch (action.type) {
    case 'INCREMENT':
      return { ...state, count: state.count + 1 };
    case 'DECREMENT':
      return { ...state, count: state.count - 1 };
    default:
      return state;
  }
};

How do I connect my React components to the Redux store?

Use the connect function from react-redux to map state and dispatch to your component's props.
