// This gist aims to explain how it's possible that async functions inside React
// using createFetcher(Promise).next(key) can work.

// A possible implementation of the new createFetcher function
// as shown by https://twitter.com/jamiebuilds/status/969169357094842368
// @param method, should be a function returning a Promise.
// @returns an object with a property 'read', used to read values from the resolved 'cache'.
const createFetcher = function(method) {
  // First create a Map for the resolved values.
  const resolved = new Map()

@kangax's ES6 quiz, explained

@kangax created a new interesting quiz, this time devoted to ES6 (aka ES2015). I found this quiz very interesting and quite hard (made myself 3 mistakes on first pass).

Here we go with the explanations:

Question 1:

(function(x, f = () => x) {

davemo

var express   = require('express'),
    httpProxy = require('http-proxy'),
    app       = express();

var proxy = new httpProxy.RoutingProxy();

function apiProxy(host, port) {
  return function(req, res, next) {
    if(req.url.match(new RegExp('^\/api\/'))) {
      proxy.proxyRequest(req, res, {host: host, port: port});
