 * Google page speed showed I have a 23 java blocking scripts resources. This website
   told me I need to copy and paste this code into my website’s HTML.
 * [https://varvy.com/pagespeed/defer-loading-javascript.html](https://varvy.com/pagespeed/defer-loading-javascript.html)
 * This is the code it told me to use.
 * <script type=”text/javascript”>
    function downloadJSAtOnload() { var element 
   = document.createElement(“script”); element.src = “defer.js”; document.body.appendChild(
   element); } if (window.addEventListener) window.addEventListener(“load”, downloadJSAtOnload,
   false); else if (window.attachEvent) window.attachEvent(“onload”, downloadJSAtOnload);
   else window.onload = downloadJSAtOnload; </script>
 * My question is how do I need upload this to my HTML so my website can be up and
   running again fast? I’m newish to web development so please bare with me on this..

 * My WP made me erase WP Cache, so that didn’t work. I tried using Async JS and
   CSS plugin and that didn’t work either. Any help would be greatly appreciated
   it!
