Thank you very much for the explanation! I was confused because I didn't realize that, actually, a class in ES6 is just a variable. Also, I am not used to the decorator pattern. Now it makes sense.

It's even worse - classes in ES6 are just functions (their constructors); 'obj = new Class()' is just sugar for 'obj = {}; Class.bind(obj)()'. So if you leave off the "new", you'll end up clobbering whatever 'this' defaults to, which is usually the global window object.

  Actually, if you leave off the "new" you get a TypeError: TypeError: Class constructors cannot be invoked without 'new'

    Depends on your browser and/or transpiler :-) That's definitely much nicer than the old way.
