What is immutability in React and why is it important?

Immutability in React refers to the concept of not modifying existing data structures. Instead, you create new ones. This is important because it helps React optimize rendering and improves performance.

Can you give me an example of how to implement immutability in a React component?

Sure! Instead of modifying the state directly, you can use methods like setState with a new object. For example:

this.setState(prevState => ({ items: [...prevState.items, newItem] }));

What are the benefits of using immutability in state management?

The benefits include easier debugging, better performance due to optimized rendering, and predictable state changes, which make your application more maintainable.

Are there libraries that help with immutability in React?

Yes, libraries like Immutable.js and Immer can help manage immutable data structures in React, making it easier to work with state.
