body: <p>I have a JavaScript error that says: <code>'True' was used before it was defined</code>.
  I have this 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>var playAgain = window.confirm("Play again? OK for yes, Cancel for no.");
  if (playAgain === True) {
      loop();
