Memoization in React is an optimization technique that helps to avoid unnecessary re-renders by caching the results of function calls.

Are there any performance benefits to using memoization?

Yes, memoization can significantly improve performance, especially in components that render frequently or have expensive calculations.

What are some common pitfalls when using memoization?

Common pitfalls include overusing memoization, which can lead to increased memory usage, and not properly managing dependencies.
