[Code Review] Trying to wrap my head around promises. Here's my attempt at rewriting one somewhat nested function. I'm not sure how to stop propagation from within a promise callback so, for the rewritten version, I changed `this.controller.isActive` to reject the promise if `isActive` is `false`. I don't really know if this code even works, I w…

	ProfilerPanel.prototype = {
	stopProfiling: function () {
	this.controller.isActive(function (err, isActive) {
	if (err) {
	Cu.reportError("ProfilerController.isActive: " + err.message);
	return;
	}

	if (!isActive) {
	return;

Destructuring with bound functions, yay/nay?

	function bind(obj) {
	let bound = {};

	for (let key in obj) {
	bound[key] = typeof obj[key] === "function" ? obj[key].bind(obj) : obj[key];
	}

	return bound;
	}

Which approach to cloning objects is faster? (Assuming there are no circular references, get/set, etc.)

	// Candidate 1
	JSON.parse(JSON.stringify(obj));

	// Candidate 2
	var desc = {};
	Object.keys(obj).forEach(function(key) {
	desc[key] = Object.getOwnPropertyDescriptor(obj, key);
	});
	Object.create(Object.prototype, desc);
