If you have jQuery on your website alongside Google Analytics, you’re loading two jQuery libraries without you knowing due to Google using it too on their analytics script.

Do you have a source on this? I can't believe this is true and my 2-3 google searches say it's not.

https://www.googletagmanager.com/gtag/js

Search “jQuery” in there, first result will be the copyright comment plus the version.

Is that the same JS used for Analytics? I think that's just for GTM. Here is the analytics script I see more often and it doesn't have jQuery: https://www.google-analytics.com/analytics.js

It’s the new snippet for analytics.

it doesn't export to the global namespace though:

    <script src="https://www.googletagmanager.com/gtag/js"></script>
    <script>$</script>
    ReferenceError: $ is not defined

    <script>jQuery</script>
    ReferenceError: jQuery is not defined
