Mathjs opinions

[tcab]

This seems like a nice JavaScript library for math.

I've got a couple of attempts at a web based calculator in my old projects. Perhaps bolting in this library would complete them. Then again, mathjs already have a notepad app
https://mathnotepad.com/
and such notepads seem to be the new dominant paradigm for math exploration etc these days, rather than the calculator form factor.
