Trigger useEffect hook when only one element in an array change-CodePudding

I am trying to trigger the useEffect hook only when a specific element in an array changes. Right now, I have something similar to this:

const [array, setArray] = useState(["someText", "someOthersText"]);
useEffect(()=>{
// some function to run
}, [array[0]])

It is working pretty well but I get this warning with my eslint:

React Hook useEffect has a complex expression in the dependency array. Extract it to a separate variable so it can be statically checked.

It suggests to instead of having "array[0]" put "array" in the dependencies. The problem is that I don't want to have my useEffect triggered when the array[1] changes but only the element at the index 0.

Do you have a solution to avoid this warning and still have it working correctly or it is not possible?

CodePudding user response：

I believe it is telling you to do this:

const [array, setArray] = useState(["someText", "someOthersText"]);
let item = array[0];
useEffect(()=>{
// some function to run
}, [item]);
