You are passing the data to the App, but not actually using it in the JSX.

export default class App extends Component {

  constructor(props) {
    super(props);
  }

  render() { 
    const {name, age} = this.props;
    return (
      <div>
        <h1>Hello {name}</h1>
        <p> Your age is {age}</p>
      </div>

    ); 
  } 
}

ReactDOM.render(<App name="john" age="37"/>, document.getElementById('root'));
