UseEffect and React Query. Explain simply. Human builds component. Component needs data. Component fetches data from server. Data comes back. Component happy. Human clicks away. Human clicks back. Component mounts again. Component fetches again. Same data. Fetch again. Server confused. Server says, I just gave you this. Human adds loading state. Human add error state. Human add empty state. Three states, one fetch. Human copy-paste same fetch logic into component two. Component three, same fetch. Component four, human forgot error state. Component four now silent when it breaks. Two tabs open. Tab one updates data. Tab two still shows old data. Human refreshes the whole page just to see new data. Human tired. React query enters. Component asks once. React query remembers. Component two asks the same thing. React. query says I got you here no refetch no duplicate no stale data sitting around confused data change somewhere react query notices react query updates everywhere same time use effect and react query both important use effect fetches data react query manages data now one component maybe no react query two components still no react query 10 components sharing the same data now react query makes sense follow for more
