Extra clarification

[andrespch]

Hey @lokhmakov, I was wondering if you could explain 2 of the things you did while creating the package, why is that we need to eject the app? from what I see we can run bable against our sources without ejecting, the second questions is why do we need to create the package.json files per component. I'm fairly new to JS and React Native, so please understand if these quesitons are too obvious.
