Summary: JS API very similar to web workers and node's child process. Work has been done by somebody else for the Android implementation over at #7020, so we'd need to have these in sync before anything gets merged. I've made a prop `messagingEnabled` to be more explicit about creating globals—it might be sufficient to just check for an onMessage handler though.  Closes https://github.com/facebook/react-native/pull/9762 Differential Revision: D4008260 fbshipit-source-id: 84b1afafbc0ab1edc3dfbf1a8fb870218e171a4c
