Can't Use Useref As Componentdidupdate Replacement

Error Uncaught TypeError: Object(...) is not a function import { useSelector, useDispatch, useRef } from 'react-redux' const mounted = useRef(); useEffect(() => {

Solution 1:

useRef is a React hook. Change to:

importReact, { useRef } from'react';
import { useSelector, useDispatch } from'react-redux';

Solution 2:

You should access your ref using mounted.current. Since you are not initializing it a value, it will return undefined.

If you are assigning your ref to a JSX element, you will not be able to access it until the DOM has loaded. In that case, I would suggest using the useLayoutEffect hook, since it will not run until the DOM has loaded.
