I have tried to load js asynchronously in Magento 2 following a recommendation from the Google PageSpeed Insights tool. Unfortunately my updates in the relevant layout file break the page.
CURRENT LAYOUT XML
<head> <script async src="js::myown.js"/> <script async src="js::another.js"/> <script async src="js::afinal.js"/> </head>
Can someone please recommend a solution to the above to get the async loading working?
