    <p>This page demonstrates creating a functional component using React Hooks.</p>

    <!-- We will put our React component inside this div. -->
    <div id="component_container"></div>

    <!-- Load React. -->
    <!-- Note: when deploying, replace "development.js" with "production.min.js". -->
