Title: Parsing Javascript question Last modified: November 11, 2020 --- # Parsing Javascript question * Resolved [happynaturaldog](https://wordpress.org/support/users/happynaturaldog/) * (@happynaturaldog) * [5 years, 7 months ago](https://wordpress.org/support/topic/parsing-javascript-question/) * Hi Gabe, I was reading about your Asset Cleanup plugin and I’m wondering if the free version provides Javascript parsing? Or what the free version provides over and above W3 Total Cache and Cloudflare? My website is only a year old so is not at a point where I can afford the pro version, so am trying to see what the lite version offers if I already have W3 and Cloudflare. Thanks!

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 (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/](https://assetcleanup.com/docs/)). In combination with W3 Total Cache and Cloudflare, it would make a difference in the PageSpeed score considerably. * Thread Starter [happynaturaldog](https://wordpress.org/support/users/happynaturaldog/) * (@happynaturaldog) * [5 years, 7 months ago](https://wordpress.org/support/topic/parsing-javascript-question/#post-13649556) * 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!
