Summary: This is an improvement to basic components docs. * I updated the basic components example code to better render components on iOS (added paddingTop). * I also modified the code to allow reader to easily copy, paste, and then run the code in their project if they followed the 'Getting Started' quick start guide. * I also added additional copy to clarify suggested usage/guidelines.

A View is the most basic building block for a React Native application. The View is an abstraction on top of the target platform's native equivalent, such as iOS's UIView.
A
Viewis analogous to using a<div>HTML tag for building websites.
It is recommended that you wrap your components in a View to style and control layout.
The example below creates a View that aligns the string Hello in the top center of the device, something which could not be done with a Text component alone (i.e., a Text component without a View would place the string in a fixed location in the upper corner):
import React from 'react';
import { AppRegistry, Text, View } from 'react-native';
const AwesomeProject = () => {
return (
<View style={{marginTop: 22, alignItems: 'center'}}>
<Text>Hello!</Text>
</View>
);
}
// App registration and rendering
AppRegistry.registerComponent('AwesomeProject', () => AwesomeProject);
