React Query Basics in react

React Query (TanStack Query) is a powerful data-fetching and state management library for 'Server State'. It simplifies the process of fetching, caching, synchronizing, and updating server data in your React applications. It replaces the traditional pattern of using many useEffect and useState hooks for data fetching with a more declarative and efficient approach.

const { data, isLoading, error } = useQuery({
  queryKey: ['todos'],
  queryFn: fetchTodos
});
