While it's not a great tool to teach people the concepts of OOP...
I actually think it's a very good tool for teaching OOP. It doesn't have types to confuse the issue, it favours composition over inheritance by design, and it fully encapsulates state.
You could do much worse than JS as a teaching language. In fact, I'd say that it was only through practical application in JS that I fully appreciated the concepts extolled by Smalltalk, Self, and Lisp. Had I worked in a Java environment I may not have had those insights until much later.
