Implement a universal React hook useFetch for GET requests. Think through a convenient API for the hook, returned data/loading/error, handling HTTP errors, and refetching data when the URL changes.
СБЕРHow to prevent race conditions in useFetch if the URL has changed, the second request finished earlier than the first, and the first then overwrote the current data?
