How do React Hooks work with immutable data?

React Hooks allow you to manage state and side effects in functional components. When working with immutable data, you can use hooks like useState to create state variables that don't mutate directly. Instead, you create new copies of the data when updates are needed.

Can you give me an example of using useState with immutable data?

Sure! Here's a simple example:

const [items, setItems] = useState([]);

const addItem = (newItem) => {
  setItems(prevItems => [...prevItems, newItem]);
};

In this example, setItems creates a new array with the existing items and the new item, preserving immutability.

What about using useReducer for more complex state management?

Great question! useReducer is perfect for managing complex state. It allows you to handle state transitions in a more structured way. You can define a reducer function that returns a new state based on the action dispatched, ensuring immutability.

Are there any libraries that help with immutable data in React?

Yes, libraries like Immutable.js and Immer can help manage immutable data in React. They provide utilities to work with immutable structures and make state updates easier.
