While impressive and seemingly well put together, I can't help but think that if you're doing numerical computation like this, JS is simply not the way to go.

I have a system that does complex simulations on a cluster running numpy, and I'd love to be able to kick an ndarray back to the frontend and it be able to do translations of that data in response to users toggling sliders.

Are you not able to use a Jupyter Notebook with ipywidgets library for this?

That relies on a python backend.

So what? They stated they were running numpy, so the scaffolding is already there.
