title: Why Hello World is not showing up?
body: <p>This is the same code as from the youtube tutorial,<br>
  but it's not working for me:</p>
  
  <p>Hello World is not showing up in the browser.</p>
  
  <pre><code>import React from 'react';
  
  function myComponent() {
    return(
    &lt;h1&gt;Hello World&lt;/h1&gt;
    );
  }
  
  class App extends React.Component {
     render(){
      return(
        &lt;myComponent/&gt;
      );
     }
  }
  
  export default App;
  </code></pre>
