1. What is TanStack Query?

TanStack Query is a library used to fetch, cache, update, and manage server data in React applications.

It was previously known as React Query .

When we fetch data from an API using Axios or fetch() , we usually need to manage loading, error, and data states ourselves. TanStack Query helps manage these tasks and provides features such as caching and automatic refetching.

2. Why do we use TanStack Query?

Fetching data: Gets data from an API.

Caching: Stores previously fetched data to reduce unnecessary requests.
