This article didn't demonstrate any risks involved in using 'class' in Javascript by devs familiar with other OOP languages. What exactly is the non-common feature in Javascript OOP that exists in other OOP languages and therefore poses such a risk that makes developes make "a lot of mistakes"? It's not messing around with prototypes, since those devs don't understand that any way.

Sounds like Javascript dev who is pissed because the language evolves and his prototype-hack-knowledge becomes more and more obsolete.
