I suppose there will be no js code within IOS folder. All JS code contained in higher level folder.
So, IOS files in IOS folder, andoid files in Android folder. JS files in other folders.
@sirmong is correct! You can still edit the JS files, but also have access to the native iOS files now that you’ve ejected. You can read more about it here -> https://docs.expo.io/versions/latest/expokit/eject/
