I have this code for eliminating render-blocking JavaScript. I've tried but it but did not work for me. Please show me how to use it. I have 3 files need to eliminate roe.js, replaceMobileFonts.js, and menu.js. Thank you

<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>
