I wouldn't be so sure... it is written in coffeescript after all. God forbid.
edit: i'd just add that even though it's only a joke, a comment regarding (even if critical of) the language used to write the code is absolutely on topic.
On the other hand, CofeeScript may have spurred many of the sweeping changes in ECMAScript 6 & 7.
On the other hand, are JavaScript classes actually a step backwards? Go doesn't have classes.
On the other hand, Go is an abomination.
