@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) {

vvscode

// что возвращает эта функция?

(function fun(Infinity, length, __proto__)
{
    return [,,~0.[0|0]][fun.__proto__.length && Infinity, -~String(this).length >> __proto__] << (0. === .0) + Infinity;
}).apply(typeof fun, [,,2]);

// рассмотрим массив с аргументами:
// "0" in [,,2] => false
// "1" in [,,2] => false

vvscode

// In global NS to make debug more easier 
var PAGES_DELAY = 3000;
var profiles = [];

function step1() {
    console.log(`Process page: ${window.location}`);
    $('a[href*="/profile"]').toArray().forEach((a) => profiles.push(a.getAttribute('href')));
    console.log(profiles.length, $('a[href*="/profile"]').length);
    if(!$('a.page-link.next').length) {
        return;
