Hmm looks like similar to python. I hope something like pandas also come to, so that I can do all complex claculations client side instead of doing it with python backend

This may be a 20th century viewpoint, but I would hesitate to call anyone who couldn't write all of these functions a programmer.

Introducing network round trips to use convenient syntax seems ... suboptimal.

Using pandas or numpy is more than uisng optimal syntax

There is a reason why python is used for ML for mathematical calculations. You could do all low level matrix multiplication using custom functions uisng any language. But is that optimal way to dob that.

My use case is similar

Fair enough; where's the breakeven?
