Hello,

You can output result directly on the page, maybe put this value in a span tag. Note that script should execute after DOM completed loaded.
In my example bellow, the script run after span tag added to the page.
If something is not working, try to investigate errors in developer console(For open console in Google Chrome Press Ctrl+Shift+J (Windows / Linux) or Cmd+Opt+J (Mac).
  
<span id="myspan"></span>
<script>
  var result = myFunction(4,5);
  var span = document.getElementById("myspan");
  var resultNode =  document.createTextNode('' + result);

  span.innerHTML = '';
  span.appendChild(resultNode);
</script>
If it helped you, then please select it the best answers it will help outer also.

Thanks,
Alex
