What is ReactJS ?
• Library for building User Interfaces
• V part of MVC ( Model View Controller )
• Not a front end framework
• Built by Facebook for internal usage first
• Full Virtual DOM
• Can be used in any other framework as the View component
• Separation of Concerns
Motivation for React
Nowadays JS is very fast and new ES6 recommendation introduces powerful OOP principles
Main drawback is DOM, till now no complete standardisation has been made in DOM APIs
DOM updates are slow
Applications are growing ever complex and data intensive

• IOS
• $ react-native run-ios
• edit index.ios.js
• Android
• $ react-native run-android

15. MOBILE MEETUP React Native
Platform Specific Code
15
• You can choose your method for keeping platform
specific code organised
• /common/components
• /android/components
• /ios/components
React Native provides a cleaner way to do that using
platform specific extensions - .ios.js & .android.js
MyCustomButton.ios.js & MyCustomButton.android.js
import MyCustomButton from ‘./components/MyCustomButton’;
• MyCustomButtonIOS.js
• MyCustomButtonAndroid.js
