The basis of my complaint is that some things are well designed, others are just nicely documented.

moment has a, to me, counterintuitive "hidden" type system that is a different-kind-of-menacing. In code I've had to review and maintain, the moment parts or more than often a soupy mess of the previous coders in combat with the nuanced hairy complexities of the library as opposed to straightforward execution of the api (compare to say, jquery, where setting all architectural disagreements aside, there's no substantial evidence of frequent "programmer struggle" in the codebases using it)

This leads to poor long-term maintainability as the code passes through many hands over the years.

If, after a year or two of average "blue collared" programmers touching a codebase it gets so convoluted that you generally need to abandon it, then fundamentally you are using poorly designed tools.

Again, we all only have our own personal lived experiences to make such assessments on, and I way too often end up "debating" what mostly amounts to my work history of parachuting in and rescuing code (it's a psychiatric problem I have) so the pessimistic aspects become quite sharp to me.
