What is the difference between mutable and immutable data in React?

In React, mutable data can be changed directly, while immutable data cannot be changed once created. This affects state management.

Can you give me an example of mutable and immutable data?

Sure! An array is mutable; you can change its elements. A string is immutable; any change creates a new string.

Why is immutability important in React?

Immutability helps with performance optimizations and makes it easier to track changes, leading to more predictable UI updates.

How can I implement immutability in my React app?

You can use libraries like Immutable.js or use spread operators and methods like concat to create new arrays or objects.
