In addition to your list here, I am drawn by ES6 on the backend. This is not javascript of the early days.

On Differentiable Programming, you might be aware of a tensorflow counterpart in javascript:

I tested this to a certain extent and its not a toy. Its well thought out product from a very talented team, and has the ease of coding that we love about javascript. It can run on browsers!

This being said, we should note the strengths of a statically compiled language with the ease of installation and deployment like with Go, Rust, Nim, etc. in enterprise scale numerical computing.
