// Question 10: React Query
What is React query for?
React Query is a data-fetching and state management library for React applications that simplifies fetching, caching, and updating data

The combination of local caching and background refetching makes React Query a powerful tool for managing data fetching in React applications. It can help you to improve performance, reduce API calls, and ensure that your data is always up-to-date

Why is useQuery used?
useQuery is a custom hook within React Query used to fetch data in a React application. Under the hood, these hooks manage lots of things such as caching data after the initial fetch, re-fetching data in the background, etc.

Why use React query over useEffect?
Additionally, React Query eliminates the requirement for useState and useEffect hooks and substitutes a few lines of React Query code in their stead. In the long term, it will unquestionably assist you in maintaining a quick, responsive, and maintained application.
