I doubt you would be able to do "systems" level programming in either JavaScript or Python.

If you are thinking of cross-compiling, then you could look at Go from Google - it has many of the advantages of C, yet a lot of conveniences afforded by Python and similar languages.

I'm fairly sure they're not writing device drivers or TCP/IP stacks, so they likely don't depend on a systems level language. A lot of work has gone into enabling people to write their apps using these interpreted languages, but the availability of one particular language or runtime on a mobile device is not always guaranteed.

I think they're asking what their options are, really.
