Fetching Data with the useQuery Hook

A query is a named request for server data that React Query runs, stores and keeps current for you. You declare a query with the useQuery hook, and the hook returns the data together with values that describe where the request stands. Before a component can declare a query, the app needs a cache to put the results in.
