JavaScript

When I run this code, a error is appear: Minified React error #200; visit https://reactjs.org/docs/error-decoder.html?invariant=200 for the full message or use the non-minified dev environment for full errors and additional helpful warnings. I didn’t understand this error. I am a newbie. Please help me. Thank you very much.

This is your code:



class TypesOfFood extends React.Component {
  constructor(props) {
    super(props);
  }
  render() {
    return (
      <div>
        <h1>Types of Food:</h1>
        {/* change code below this line */}
          <div>
            <Fruits />
            <Vegetables />
            </div>
        {/* change code above this line */}
      </div>
    );
  }
};
ReactDOM.render(<TypesOfFood />, 'challenge-node');
// change code below this line

The second argument for ReactDOM.render is an actual DOM node (like the value you get when calling document.getElementById), not just a string
