Developing a mobile application with a cross platform technology is the right move that saves time, money and maintenance on both platforms. Nothing is better than devising the applications leveraging JavaScript but that holds true when you are developing Web Apps not Mobile Apps. Facebook’s React Native has broken this barrier by allowing the use of JavaScript to write mobile apps.

The main difference between a WebApp and React Native is the use of native UI components instead of HTML. React Native uses the same building blocks for the UI as any native code would. So you get the look, feel and performance (UI-wise) of a native app, because the UI is native.

Why React native and not any other technology?

It gives us many solutions that other technologies cannot afford. Here is what you can do with React Native:

Building native mobile apps
React Native allows us to write native apps in JavaScript for both iOS and Android. It gives us the ability to use all the native components like gestures, push notifications, camera, and location. There are some other JavaScript libraries for building mobile apps like ionic or PhoneGap. But those libraries use Webview, and the apps built with those technologies are not native.

Building cross platform mobile apps (iOS and Android)
Yeah, with React Native you can build mobile apps that can run on iOS and Android. This is one of the great benefits of React Native. Before Facebook created it, you had to build your app twice and with different code: one for iOS using Swift or Objective-C and one for Android using Java or Kotlin. React Native solved this problem so you can build your React Native app and it will work in iOS and Android.

Write your code all in JavaScript and React
While you are building React Native apps, you will actually write JavaScript. Reactjs code allows us to build great UI and user experience components. It is an open source framework, which could be compatible with other platforms like Windows or tvOS in the near future.

Since the UI is native, performance is comparable with native apps. React Native is a framework that builds a hierarchy of UI components to build the JavaScript code. It has a set of components for both iOS and Android platforms to build a mobile application with native look and feel.
