moment's given me no trouble at all. I certainly haven't found it to be full of traps. Addressing the most common complaint: a moment object is mutable, sure - that's a valid design choice, not a trap. Follow the docs and everything works perfectly well IME.

As a specific point, I have not safe found a way to represent a date or time in Moment. When I point this out, I generally get agreement from people who are more used to other languages, and the claim that "You should never be representing a date or time; everything should be a datetime" by JS devs.
