ES6 Destructuring and Module imports

by 
import {Link} from 'react-router';

imports a named export from react-router, i.e. something like

export const Link = 42;

import Router from 'react-router';
const {Link} = Router;

pulls out the property Link from the default export, assuming it is an object, e.g.

export default {
  Link: 42
};

(the default export is actually nothing but a standardized named export with the name “default”).

See also export on MDN.

Complete example:

// react-router.js
export const Link = 42;
export default {
  Link: 21,
};


// something.js
import {Link} from './react-router';
import Router from './react-router';
const {Link: Link2} = Router;

console.log(Link); // 42
console.log(Link2); // 21

With Babel 5 and below I believe they have been interchangeable because of the way ES6 modules have been transpiled to CommonJS. But those are two different constructs as far as the language goes.
