Sometimes, when a user attempts to open a website, it can take a long time for the website to load. This slow loading time can be frustrating for the user and may cause them to avoid making purchases from the store. This ultimately leads to a negative user experience, which can lead to fewer sales or conversions.


MageAnts Magento 2 Defer Parsing of JavaScript allows store owners to make their website run smoothly, reduce the loading time, improve the store performance, and speed up to boost sales by loading the HTML and CSS before JavaScript.
