@Justine It will make your development process more easier than doing everything with React native directly. It won't allow you to add stuffs in Java or Object-c like you may already did with just React Native, you have to write everything in JavaScript, and the other stuffs that you find yourself forced to write in other native languages or platform oriented languages like Java and Objective-c are already implemented in exponent and you can call them directly think of it like cordova or phonegap but more native.
