What are React Hooks and how do they relate to immutability?

React Hooks are functions that let you use state and other React features without writing a class. Immutability is crucial in React because it helps to optimize performance by preventing direct state mutations.

Can you explain why immutability is important in React?

Immutability helps React determine when to re-render components. By ensuring that state is not mutated directly, React can efficiently compare previous and current states.

How do I implement immutability with React Hooks?

You can use the useState hook to manage state immutably. For example, when updating an array, create a new array with the updated values instead of modifying the existing one.

Are there libraries that can 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.
