Hi Matt, the JS was Google Analytics tracking code. I get NO traffic but I like to have analytics there just for fun. I am a web developer, though, and would like to have a way to add on JS I write if I want to make a custom widget or something for the front end.
<!-- Global site tag (gtag.js) - Google Analytics -->
<script async src="https://www.googletagmanager.com/gtag/js?id=UA-XXXX-1"></script>
window.dataLayer = window.dataLayer || ;
gtag('js', new Date());
