React is a JavaScript library for building user interfaces. 
It is maintained by Facebook and a community of 
individual developers and companies. 
React can be used as a base in the development of single-page 
or mobile applications.

  render() {
    return (
      <div className="shopping-list">

        <ul>
          <li>Instagram</li>
          <li>WhatsApp</li>
          <li>Oculus</li>
        </ul>
      </div>
