How do I use Redux in my React application?

To use Redux, first install it via npm. Then, create a store and provide it to your app using the Provider component.

What are the main concepts I need to understand?

You should understand actions, reducers, and the store. Actions are payloads of information, reducers specify how the state changes, and the store holds the state.

Can you give me an example of an action and a reducer?

Sure! An action could be { type: 'ADD_TODO', payload: 'Learn Redux' }. A reducer for this action might look like function todos(state = [], action) { if (action.type === 'ADD_TODO') { return [...state, action.payload]; } return state; }.

How do I connect Redux with my React components?

You can use the connect function from react-redux to connect your components to the Redux store, allowing them to access state and dispatch actions.
