React Native - App
If you open the default app you can observe that the app.js file looks like
import React from 'react';
import { StyleSheet, Text, View } from 'react-native';
export default class App extends React.Component {
   render() {
      return (
         <View style = {styles.container}>
            <Text>Open up App.js to start working on your app!</Text>
            <Text>Changes you make will automatically reload.</Text>
            <Text>Shake your phone to open the developer menu.</Text>
         </View>
      );
   }
}
const styles = StyleSheet.create({
   container: {
      flex: 1,
      backgroundColor: '#fff',
      alignItems: 'center',
      justifyContent: 'center',
   },
});
Output
 
Hello world
To display a simple message saying “Welcome to Tutorialspoint” remove the CSS part and insert the message to be printed wrapped by the <text></text> tags inside <view></view> as shown below.
import React from 'react';
import { StyleSheet, Text, View } from 'react-native';
export default class App extends React.Component {
   render() {
      return (
         <View>
            <Text>Welcome to Tutorialspoint</Text>
         </View>
      );
   }
}
