FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

Long Live CoffeeScript and Long Live ES6

Clearly ES6 is a huge improvement over ES5, and tools like [6to5][] allow us to use these cool features now. I was reading [Replace CoffeeScript with ES6][replace coffeescript] by [Blake Williams][] and thought it was a great summary of how ES6 solves many of the same problems that CoffeeScript solves; however I'd like to comment on a few of Blake's points and talk about why I'll be sticking with CoffeeScript.

Classes

Classes in ES6 (like many of the syntax changes in ES6) are very similar to the CoffeeScript equivalent. To support browsers that are not fully ES5 compliant (e.g. IE8-), however, we still can't really use getters/setters, so ignoring these the comparison is:

	/*<?php
	///public class PhpJava { public static void main(String[] args) { System.out.printf("/%s",
	//\u000A\u002F\u002A
	class PhpJava {
	static function main() {
	echo(//\u000A\u002A\u002F
	"Hello World!");
	}}
	//\u000A\u002F\u002A
	PhpJava::main();
