In the following paragraphs, We'll see how useQuery can ease our task in polling and refetching APIs conditionally with a small illustration. We will now dive into the requirements with out further more ado.
If we influence ourselves to utilize Respond Query, then these operations become all the more easier with a several lines of useQuery: it’s remarkably configurable with lots of batteries involved.
