How to implement useEffect so the list on the front page updates only when a name change has been detected

Question

A page displays a list of objects [{name:, age:}, ...] A second page allows to update the name of a particular object. Then using hooks, how should I implement useEffect() so the list on the front page updates only when a name change has been detected?

const [objects, setObjects] = useState([]);

useEffect(()=> {
  getAllObjects()
},[getAllObjects, objects]);

Hello @kartik,

Instead of passing the entire object to the dependency array, make sure that you only pass name which you can do by returning the names:

const [objects, setObjects] = useState([])

useEffect(()=> {
      getAllObjects()
}, [getAllObjects, ...objects.map(item => item.name)])

Thank You!!
