TLDR: Use for...of instead of forEach in asynchronous code.

Array.prototype.forEach is not designed for asynchronous code. (It was not suitable for promises, and it is not suitable for async-await.)

For example, the following forEach loop might not do what it appears to do:

	const puppeteer = require("puppeteer");

	// This works around Discord's security measurements
	// to set values on localStorage before we go to discord.com/login
	const setDomainLocalStorage = async (browser, url, values) => {
	const page = await browser.newPage();
	await page.setRequestInterception(true);
	page.on("request", r => {
	r.respond({
	status: 200,

	var nextChar = c=>c?String.fromCharCode(c.charCodeAt(0)+1):'A';
	var nextCol = s=>s.replace(/([^Z]?)(Z*)$/, (_,a,z)=>nextChar(a) + z.replace(/Z/g,'A'));

	//test:

	nextCol(''); //A
	nextCol('A'); //B
	nextCol('Z'); //AA
	nextCol('AA'); //AB
	nextCol('XYZ'); //XZA
