Description
Hello,
it would be nice, if Googles "defer parsing of javascript" find its way into the core of TYPO3.
config.deferJS = TRUE / FALSE
Here is the reference link: https://developers.google.com/speed/docs/best-practices/payload#DeferLoadingJS
<script type="text/javascript">
// Add a script element as a child of the body
function downloadJSAtOnload() {
var element = document.createElement("script");
element.src = "deferredfunctions.js";
document.body.appendChild(element);
}
// Check for browser support of event handling capability
if (window.addEventListener)
window.addEventListener("load", downloadJSAtOnload, false);
else if (window.attachEvent)
window.attachEvent("onload", downloadJSAtOnload);
else window.onload = downloadJSAtOnload;
</script>

as there are different techniques now (also recommended by google) nothing to do for the core for now.
