React Native:

If you want to build mobile apps for both Android and iOS. What should you learn? The individual native languages for each app i.e, Java for Android and Swift/Objective-C for iOS?, Actually NO. Native Android and iOS development are quite different and can be expensive – first, the language itself is quite different, and second, all the underlying APIs are different – the way of using the GPS is different, the way to create animations is different, the way you make network calls is different.

We’re always looking for shorter development cycles, quicker time to deployment, and better app performance. And there are so many hybrid mobile frameworks such as NativeScript, React Native, Ionic, Xamarin, PhoneGap, etc.

React Native: It is a framework developed by Facebook for creating native-style apps for iOS & Android under one common language, JavaScript. Initially, Facebook only developed React Native to support iOS. However, with its recent support of the Android operating system, the library can now render mobile UIs for both platforms.

Prerequisite:
1. Basic Knowledge of HTML, CSS and JS.
2. Basic Knowledge of ReactJS.
3. NodeJs should be installed in your system.

Building with React Native is extremely efficient and highly addictive but getting started can be a little tricky. React Native uses Node.js, a JavaScript runtime, to build your JavaScript code. If you don’t already have Node.js installed, it’s time to get it!
