> Google Analytics Tracking Code
> ga.js is a legacy library. If you are starting a new implementation, we recommend you use the latest version of this library, analytics.js. For existing implementations, learn how to migrate from ga.js to analytics.js

Universal Analytics is the new operating standard for Google Analytics; however, many sites and applications still use outdated tracking libraries to send data to Google Analytics.

It is strongly recommended that you upgrade to use a Universal Analytics tracking library such as analytics.js or the latest mobile SDKs for Android and iOS.
