@happynaturaldog I’m not sure exactly what your goal is and what kind of JavaScript parsing are you referring to. The plugin does not support adding new JavaScript files to load as it deals only with existing assets. Its purpose is to clean things up.
It can help you defer parsing of JavaScript files if that’s what you mean. In case you’re combining JS files, it has the following option available: “Defer loading JavaScript combined files from <body> (applies defer=”defer” attribute to the combined script tags)“. However, when it comes to choosing individual files to defer which is a more advanced method and often the recommended one, you need the Pro version which has support for adding attributes to the SCRIPT tags including “defer” and “async”.
If you’re planning on using only the Lite version, then my recommendation would be to unload the CSS/JS that is not needed (docs here: https://assetcleanup.com/docs/). In combination with W3 Total Cache and Cloudflare, it would make a difference in the PageSpeed score considerably.
Thanks for the quick reply Gabe and the information. As you can tell, I’m not a tech person, so am still learning what all these terms mean – so your explanations were helpful!
