As a veteran C++ developer, I actually quite enjoy Javascript. Once I understood that Prototypes are linked lists and that *this is a pointer that changes according to 2 simple rules, Javascript became quite easy. I mean they even give you a GUI debugger. It's hard to get stuck for long, even though it's not not a Visual Studio. Like you said, you have already all the abstractions you need with this language. You can do complex things and for me, if I have composition, I'm pretty much already good to go.
