Javascript library for QM calculations

In summary, the conversation is about finding a good javascript library for developing technically accurate animations. The speaker mentions their preference for things to happen in the browser and their interest in using linear algebra and numerical integration with operators. They also mention the need to represent results in numbers and calculate expectation values. Lastly, the speaker mentions their wish for a library that can generate random samples according to a distribution function. The recommended resources are P5js.org and numjs, both of which have libraries for animations and are functionally similar to numpy.

Does anyone know of a good library in javascript that would help to develop technically accurate animations? I know there is stuff in python, but I'd like things to happen in the browser.

Apart from linear algebra with complex valued matrices and vectors, I'd like to have things like numerical integration with operators inside the integrand, e.g.
##\int d\omega~f(\omega)~a^\dagger(\omega) ~|\psi\rangle##

Come to think of it, how would one actually represent that result in numbers?
Anyway, finally I would need to calculate expectation values based on that kind of integral, after applying some measurement operator to it.

Another thing on my wish list would be to generate random samples according to a distribution function.

Your best bet would be to checkout P5js.org

They have a support library for animations.

And there numjs that is functionally similar to numpy

Thank you --- I will look at these two resources.
