heres some platform apis react-native sets up, good targets for attenuation https://github.com/facebook/react-native/blob/73108477589a18cecb303ef556fa3da02f8ca1b8/ReactCommon/jsiexecutor/jsireact/JSIExecutor.cpp#L85-L137

I am not a React user, not well versed in React, and certainly not in React Native. How would I reproduce?

[kumavis]

@erights the incompatibilites can all be addressed by configuring or modifying react-native/metro, and ensuring ses itself is not transformed. so maybe we can close these issues. these were uncovered as part of our look at lavamoat-react-native, but that effort currently does not have a champion

Please @kumavis, do add this issue to the index

#1018

[bentobox19]

Please @kumavis, mark #663 as done: It is a RN issue where we need to tell it to not transform the arrow functions at node_modules/promise/setimmediate/es6-extensions.js, or discard entirely the transformation. See #663 (comment) for more details.

[bentobox19]

#699 can be marked as done as well, @kumavis.
