How can I optimize fetch calls in my React application?

You can optimize fetch calls in React by using techniques like caching, debouncing, and using the useEffect hook efficiently.

What is caching and how can I implement it?

Caching involves storing the results of fetch calls so that subsequent requests can be served faster. You can use libraries like SWR or React Query for this.

Are there any best practices for using the useEffect hook with fetch?

Yes, ensure you include the necessary dependencies in the dependency array and clean up any subscriptions to avoid memory leaks.

Can you give me an example of using SWR for data fetching?

Sure! Here's a simple example: const { data, error } = useSWR('/api/data', fetcher); where fetcher is a function that fetches your data.
