What are the best practices for handling immutable data in React?

When working with immutable data in React, it's essential to use libraries like Immutable.js or Immer. These help manage state changes without mutating the original data.

Can you explain why immutability is important in React?

Immutability helps in optimizing performance by allowing React to quickly determine if a component needs to re-render. It also makes state management more predictable.

What are some common mistakes to avoid with immutable data?

Common mistakes include directly mutating state, not using shallow comparisons, and failing to update references correctly. Always return new objects or arrays.

How can I implement immutability in my existing React project?

You can start by refactoring your state management to use spread operators or libraries like Immer. Gradually replace mutable patterns with immutable ones.
