/**
 * Accessing DOM elements
 *
 * Another useful application of the useRef() hook is to access DOM elements.
 * This is performed in 3 steps:
 * 
 * - Define the reference to access the element const elementRef = useRef();
 * - Assign the reference to ref attribute of the element: <div ref={elementRef}></div>;
 * - After mounting, elementRef.current points to the DOM element.
 */

import { useRef, useEffect } from 'react';
function AccessingElement() {
  const elementRef = useRef();
   useEffect(() => {
    const divElement = elementRef.current;
    console.log(divElement); // logs <div>I'm an element</div>
  }, []);
  return (
    <div ref={elementRef}>
      I'm an element
    </div>
  );
}
