Will this be safe (considering one can upload any file)? Any potential social engineering attack vector? Is it possible to access the JS environment from Java (and e.g. steal browser cookies)?

At the moment most of the standard library is not yet implemented, there are no native functions that access network.

Ideally we only need the run tab, but due to the limitations of the type checker and compiler this was requested as a feature.

Yes, maybe this feature should only be available in the command line tool and not in sourceacademy.org? I agree that for now it's ok. Maybe we include it for the project presentation next week and then remove it?

I am planning to use localhost for presentation. I think mei tin is using the localhost approach as well. Is there a way we only enable it for dev and not production? do we have feature flags?

Not sure, does process.env.NODE_ENV work?

No we don't (at least not yet for now…)

looks like it does, added the check.
