Demonstration of some cool es7 features.

random.es7.js

require('babel/polyfill');

/**
 * Imagine this is some complex async process
 */
async function random() {
	return new Promise(r => r(Math.random()));
}

async function main() {
	try {
		console.log(Math.floor(await random() * 1000));
	} catch (e) {
		console.error(e);

main();

/** CAN ALSO BE WRITTEN AS */

main().then(::console.log).catch(::console.error);
