This is very nice for servers that need to have super large numbers, encryption, loops, and much more.
I am using this for Mining and more than half of my code relies on the DLL (if there is no DLL it'll use blockland's functions)
It takes a lot less time to generate a full sphere in javascript than torquescript (I mean.. torque is awfully slow and javascript is using its own engine of course), it's great.
Registering functions from torque to javascript is pretty neat too.
