What's difference between AppMeasurement.js and at.js?
To implement Adobe Analytics, there's one guide mentioned:
https://experienceleague.adobe.com/docs/analytics/implementation/js/overview.html
This will use AppMeasurement.js
However, there also another link:
https://developer.adobe.com/target/implement/client-side/
This will use at.js
So my question is:
what's difference between AppMeasurement.js and at.js? which case should be depending on AppMeasurement? and at.js?
Or at.js is future, AppMeasurement.js is past?
Thanks,
Kent
