const App = props => {
    const itemsRef = useRef([]);
    // you can access the elements with itemsRef.current[n]

    useEffect(() => {
       itemsRef.current = itemsRef.current.slice(0, props.items.length);
    }, [props.items]);

    return props.items.map((item, i) => (
      <div 
          key={i} 
          ref={el => itemsRef.current[i] = el} 
          style={{ width: `${(i + 1) * 100}px` }}>
        ...
      </div>
    ));
}
