Javascript developer always tried to explore platforms where Javascript can be used to build better USER experiences. React native is not the first FRAMEWORK which enables web developers to build applications for the mobile platform. Ionic, Cordova were few very popular application framework which was used to develop a mobile application using web technologies. One major motivation towards this effort was having a seamless experience on all the platforms. Mobile application developed with React Native is different than alternate frameworks in the following ways:

1. React Native app is a real mobile app, not a web app running INSIDE a mobile app shell. Other alternative like Cordova, ionic run a web app in a web view.
2. React Native app is converted into machine code which runs on mobile that is why it gives better performance than other alternatives.
3. React Native mobile APPS are more close to Native app development in comparison to other Javascript frameworks
4. Mobile application built with React native has small bundle size in comparison to older hybrid application development framework.
