What about caching in React?

In React, caching is often handled on the client side. You can use libraries like React Query or SWR to manage server state and cache responses. These libraries provide features like stale-while-revalidate, which allows you to show cached data while fetching fresh data in the background. Do you want to dive deeper into any of these libraries?

How does caching affect performance?

Caching significantly improves performance by reducing the time it takes to retrieve data. It minimizes the need for repeated database queries or API calls, leading to faster load times and a better user experience. However, it's essential to manage cache invalidation properly to ensure users see the most up-to-date information.
