A bit simplistic of a take, consider games. First client server games made server deal with logic, exclusively.

Modern (post Quake) games make server authoritative but allow server logic to run locally.

What modern JS app do is something hybrid client/server rendering. It's akin to moving/transmitting code from server for faster rendering.

I think they use it for offline web apps and to fix problems with server side rendering (usage of resource, time to first render).

We're going to have locality optimizing migrating code.
