React Native:

React native can be define as the framework of JavaScript that is used to create mobile applications for Android and iOS. The components of native app are combined in react native framework from which a developer can make react native mobile apps. React native has a set of ready-to-use components to build mobile apps for both iOS and android. On the other hand, creating user interface, ReactJS is used which is an open source JavaScript library. Facebook has introduced the React Native and React JS with different design interfaces under same design principles. Since the same code is being used for creating react native mobile apps for both android and iOS, there are three things that the developers must know to create a react native mobile app. These are:

• HTML
• CSS
• JAVA

Importance of React Native Framework

• It saves the time for development
• It renders UI for android and iOS programs
• It is an open source framework which would be compatible with other platforms in the near future
• It is simple, quick and efficient
• It is UI Focused
• Cost reduction

Why React Native?

The primary reason of using this framework is that only one set of code is to be written by the developer and that is JavaScript code.

This framework has been introduced for iOS development at first and later on Facebook has decided to give support for Android Development as well. With this, the popularity and success of the React Native Framework has increased even more as both the platforms are using a single codebase program at the same time. One of the biggest advantages of building mobile application with React Native is “Live Updates”. Developers do not have to go to the app store update cycle; they simply send the updates to the user’s mobile phones. The extensive use of JavaScript makes it easy to do so. With the use of react native, development time has been reduced. As react native is an open source program, it is providing a lot of components to use.
