From how I understand it this is not a javascript Tor implementation at all. It's an entirely different piece of software that allows you to create a whole lot of volatile short lived proxy servers that can then be used to connect to actual tor relays. The idea being that it will be really hard for censors to block proxy servers that only exist for a short period of time.
