SWR/React-Query vs Fetch + UseEffect

could you make tutorial on doing caching but without any of these libraries? cause i'm learning using this library, but still dont get how to cache a data myself, i cant find any right tutorial on caching without third-party library

Please do a tutorial of the project that you are using in this video.

dude how do you do android and react same time. Bcz many times due to muscle memory I write javascript syntax instead of kotlin yes I identify and fix that immediately but how to get rid of this 🤣

I dont see any issue with requesting when your server is fast
Also what I dont like about these caching libs is that it shows cached result, then makes a request, if there's new data, it updates it right away and thus your content just jumps

Thanks

And what about RTK Query?
