title: Error Message: document.write is disallowed in JSFiddle
body: <p>When I try to run one of my JavaScript files on JSFiddle, I get the following error message:</p>
  
  <blockquote>
    <p>document.write is disallowed in JSFiddle environment and might break your fiddle. </p>
  </blockquote>
  
  <p>How do I fix this issue?</p>
  
  <p><strong>Note:</strong> When I use external resources, it works fine. But I want to use the JavaScript panel for scripts.</p>
