To do that you first need to have a way of extending JavaScript with C and/or Fortran. No way numpy can be implemented in pure js or python without being excruciatingly slow.

You can do it with the nodejs FFI. It makes me cringe a bit to say that, but you could do it in roughly the same way as how NumPy does it.
