Formatting a Date String in React Native

The beauty of the React Native is that it supports lots of JS libraries like Moment.js.
Using moment.js would be a better/easier way to handle date/time instead coding from scratch

just run this in the terminal (yarn add moment also works if using React’s built-in package manager):

npm install moment --save

And in your React Native js page:

import Moment from 'moment';

render(){
    Moment.locale('en');
    var dt="2016-05-02T00:00:00";
    return(<View> {Moment(dt).format('d MMM')} </View>) //basically you can do all sorts of the formatting and others
}
