What version of JS does JS Use API use?

[Harry_Ho]

I am under the assumption that AEM uses some kind of special JS engine under the hood or does some kind of conversion into Java or something crazy. However, it is hard to really know what is going on through the documentation and web, so I was curious if anyone knows what version of JS the use API is?
