Summary from the TLDR Web Dev newsletter

React Query is a library for managing asynchronous states in React applications. While simple data fetching can be done without React Query, there are five potential issues when fetching data using the traditional approach with useEffect and useState. These include race conditions, lack of loading and empty states, data and error state not resetting when the category changes, and the useEffect firing twice in StrictMode. This article shows how React Query is able to fix these issues by simplifying data fetching, improving code quality, and handling these issues more efficiently - with code examples.
