@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 = () =&gt; x) {

	<!DOCTYPE html> <!-- HTML5 doctype 不区分大小写 -->
	<html lang="zh-cmn-Hans-CN"> <!-- 更加标准的 lang 属性写法 http://zhi.hu/XyIa -->

	<head>
	<meta charset="UTF-8">

	<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1" /> <!-- 优先使用IE最新版本和 Chrome -->
	<meta name="renderer" content="webkit\|ie-comp\|ie-stand"> <!-- 360 浏览器内核控制 -->
	<!--
	content的取值为webkit,ie-comp,ie-stand之一，区分大小写，分别代表用webkit内核，IE兼容内核，IE标准内核。

	//压缩js 配置
	fis.config.set('settings.optimizer.uglify-js', {
	mangle: {
	except: 'exports, module, require, define,bed,wx,jQuery,$'
	}
	});

	//自动去除console.log等调试信息
	fis.config.set('settings.optimizer.uglify-js', {
	compress: {

	if (typeof module === "object" && module && typeof module.exports === "object") {
	module.exports = exports;
	} else if (typeof define === "function" && define.amd) {
	define(['base64','template','bedtime'],function (Base64,template,bed) {
	return exports;
	});
	} else {
	window.bed.sharingInit = sharingInit;
	}

	/*
	* Replace all SVG images with inline SVG
	*/
	function replaceSvg(){
	jQuery('.up img').each(function(){
	var $img = jQuery(this);
	var imgID = $img.attr('id');
	var imgClass = $img.attr('class');
	var imgURL = $img.attr('src');

	.generate-columns(9);

	.generate-columns(@n, @i: 1) when (@i =< @n) {
	.float@{i} {
	animation: ~'float@{i}' 5s ease-in-out infinite;
	}
	.generate-columns(@n, (@i + 1));
	}

	result :

	#rotate(@deg){
	transform: rotate(@deg);
	}

	@myWiggle: {
	10% { #rotate(14deg); }
	100% { #rotate(0deg); }
	};

	wawa.Router = function(){
