I’m running Weaver Xtreme on 3 sites. I’m trying to make them load faster and pass Google’s Core Web Vitals. As a part of that, I’ve found a tool that looks for synchronous JS files. It’s identified the below two files. Is there way to make them into asynchronous JS files?
It is my understanding that the main performance issue is if scripts are loaded at the beginning of page load (commonly called above the fold) or at the end, after all the other HTML has been loaded.
weaverxjslib.min.js must be loaded at the top for optimal performance, while weaverxjslib-end.min.js does load at the end.
I don’t really understand exactly what a synchronous JS file is. Not a term I’ve heard before.
