Yeah that's mostly how things are set up. Javascript code is used to control things at a high level like the workflow of a command, hide/show different controls, etc... while the more heavy duty calculation is done at the C++ level.

But in the future I think it will be possible to do some more advanced stuff with script by growing the library of geometry related functions that are exposed to be script callable.
