How React's ES6 syntax is different from ES5 syntax?

1. require vs. Import // ES5 var React = require('react'); // ES6 import React from 'react';

2. exports vs. export

// ES5 module.exports = Component; // ES6 export default Component;

 3. component and function

// ES5 var MyComponent = React.createClass({ render: function() { return( <h3>Hello JavaTpoint</h3> ); } }); // ES6 class MyComponent extends React.Component { render() { return( <h3>Hello Javatpoint</h3> ); } }

4. props

// ES5 var App = React.createClass({ propTypes: { name: React.PropTypes.string }, render: function() { return( <h3>Hello, {this.props.name}!</h3> ); } }); // ES6 class App extends React.Component { render() { return( <h3>Hello, {this.props.name}!</h3> ); } }
