Even in OO languages (such as Java and C#) people are routinely advised to favor composition over inheritance whenever given half a chance. Classes definitely smell (or rather reek) of the infamous 90s that inflicted such atrocities on humanity as the Rational Rose "products" and the UML "methodologies". It also goes to show why the "typescript" Microsoft strategy is ill thought. Unless of course it's simply (as I think it is) the Mother of all Embrace Extend Extinguish strategies in which case it is very cleverly thought. Sadly ECMAScript has also jumped on the OO bandwagon by offering "classes" syntactic sugar but at least it is left to the developer to use it or not, whereas in the Microsoft-land of "typescript" you get classes rammed down your throat.
