Why? React and React Native are both pretty core to Facebook&#x27;s main applications these days (all of Instagram is written in React, there&#x27;s a smattering of components all over the main Facebook page, and multiple Facebook-written applications are written in React Native, including parts of the main Facebook app). In contrast, Parse was more of a dev-infrastructure product that didn&#x27;t end up impacting developer relations as much as Facebook wanted it to (I&#x27;m guessing)
