A Tale of Two Scopes

Hi, I'm an ES6 enthusiast and I'm here to explain why the convenience of one set of scope rules in JavaScript has been replaced by the convenience of two sets of scope rules.

You're probably thinking, "Sure, more scope rules are great, and I don't mind paying the extra cognitive load, but how will I remember all those rules?"

	#!/usr/bin/env ruby

	sample_size = 3000
	stay_counter = 0
	switch_counter = 0

	sample_size.times do \|i\|

	# Randomly create a scenario
	winning_door = [1,2,3].sample

	/**
	* Get a user's public GitHub activity using the GitHub API
	* Returns a promise
	*/
	function GitHubActivity(username) {
	var master, fetch, collectedData;

	collectedData = [];

	const app = new http.Server();

	app.on('request', (req, res) => {
	res.writeHead(200, { 'Content-Type': 'text/plain' });
	res.write('Hello World');
