What is the advantage of caching if the data is going to be re-fetched and it's going to cause a re-render of the component anyway? Shouldn't there be a way to check if the re-fetched data is the same so we don't need to re-render the component?

Best useQuery tutorial BY FAR out there! I have a question! U said that a background refetch is happening after a new mount but if the data is the ssme the page dont change! But it stills rerender right? So if we use memo we prevent rerenderi g?? Ty a lot !

There is a problem though..It make a call to API again and hence all the component gets rendered. It causes performance issue.

const {data, isLoading, isError, error, isFetching} = useQuery({
queryKey:['super-heroes'],
queryFn: fetchSuperHeroes,

})

how it is caching and there is a request in devtools at the start of the video?

3:05 so this helps rendering times and client side performance of the page – but is not taking any load off the API as it fires the same amount of requests as without react-query, correct?

What about the user interaction with the data ? Like we store it in useState etc and apply some on clicks etc

Thanks for nice explanation. Need to one clarification. only the results are cached? and still calls made to the back end rest api. is it comparing the results of the cached ones against the one fetched from the server
