title: I got the error unclosed regular expression in my jsfiddle
body: <p>I am new to React and jsfiddle.
  I try to program something basic in React by the JSfiddle but nothing appear on the screen and I get the errors "unclosed regular expression" and "Unrecoverable syntax error".
  I didnt find any solution or explanation, why these errors appear, not in the web and here.
  The following is the my jsfiddle:
  <a href="https://jsfiddle.net/eli12m/or9uxwch/38/" rel="nofollow noreferrer">https://jsfiddle.net/eli12m/or9uxwch/38/</a>
  Can you please tell me what i am missing.
  The following is the code:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>class InputPhoneNumber extends React.component{
   render(){
     return(
      );
    }
  }
  
  
  class ReadOnlyPhoneNumber extends React.component{
   render(){
     return(
      );
    }
  }
  
  class PhoneNumberInputDisplay extends React.component{
   render(){
     return (&lt;h1&gt;Hello World&lt;/h1&gt;); /* Here the errors */
    }
  }
  
    ReactDOM.render(
      &lt;PhoneNumberInputDisplay /&gt;,
      document.getElementById('root')
    );</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;html&gt;
  &lt;head&gt;
      &lt;title&gt;Page Title&lt;/title&gt;
      &lt;link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.1.0/css/bootstrap.min.css"&gt;
  &lt;/head&gt;
  &lt;body&gt;
    &lt;div class="jumbotron jumbotron-fluid"&gt;
      &lt;div id="root" class="container"&gt;
      &lt;/div&gt;
    &lt;/div&gt;
  &lt;/body&gt;
  &lt;/html&gt;</code></pre>
  </div>
  </div>
  </p>
