The whole thing boils down to creating objects (the constructor is built-in) and using functions on objects. Functions are objects, too. In fact, everything except primitive values are objects.

IMHO knowledge of C++, Python, or pretty much everything that's not a lisp variant, doesn't translate well to JavaScript.

There's such a nice language with its own silly warts, readily available to pretty much anyone with a computer regardless of form factor, being misunderstood by the vast majority of programmers.
