findDOMNode is deprecated and will be removed in the next major release.

findDOMNode is a method in React that allows you to get a reference to a DOM node that is rendered by a component. However, it has been deprecated and will be removed in the next major release of React.

This means that you should avoid using findDOMNode in your code and instead use other ways to interact with the DOM, such as refs or the useEffect hook. Using findDOMNode can lead to performance issues and can make your code harder to maintain.

If you need to access a DOM node in a component, you can use the useRef hook to create a reference to the node. For example:

import { useRef, useEffect } from 'react';

function MyComponent() {
  const myRef = useRef(null);

  useEffect(() => {
    console.log(myRef.current);
  }, []);

  return <div ref={myRef}>Hello World!</div>;
}

In this example, we create a reference to the div element using the useRef hook and then log it to the console using the useEffect hook.
