Summary:
Right now from JS there's no way to see the environment variables or arguments that the application was started with.
The main use case for this is to help enable/disable features when being run in a testing environment (as environment variables are the easiest way to communicate).
javache is it okay to reference these constants from JS at startup time? I am planning to disable yellow boxes via an environment variable.
achen1 how easy is it expose these two things for Android as well?
