how to reference a dom node using forward ref where the two components are in the same level

Question

When i press enter on textarea in TextArea component the focus should go in textarea of Editor.js component.
this is my parent component.

  const Content = () => {
      
      return (
        <div>
          <TextArea />
          <Editor />
        </div>
      )
    }

textarea.js (first child)

 const TextArea = () => {
        function handleChange(e){
         //if e.target.value will be that of enter , bring focus to textarea of Editor.js  
        }
        return (
        <div>
            <textarea
            onChange={handleChange} 
            />
        </div>
        )

Editor.js

 const Editor = () => {
            return (
            <div>
                <textarea/>
            </div>
            )

Answer 1

This is How you approach it:

const TextArea = React.forwardRef((props, ref) => {
  const {editorRef} = props;
  function handleChange(e) {
    //if e.target.value will be that of enter , bring focus to textarea of Editor.js
    if(editorRef.current){
      editorRef.current.focus();
    }
  }
  return (
    <div>
      <textarea ref={ref} onChange={handleChange} />
    </div>
  );
});

const Editor = React.forwardRef((props, ref) => {
  return (
    <div>
      <textarea ref={ref} />
    </div>
  );
});

const Content = () => {
  const textAreaRef = useRef();
  const EditorRef = useRef();

  return (
    <div>
      <TextArea ref={textAreaRef} editorRef={EditorRef}/>
      <Editor ref={EditorRef} textAreaRef={textAreaRef} />
    </div>
  );
};
