I mean, any scenario? I'm not trying to be snarky but server-side Javascript has always been a weird code smell from first premise. Now, when to use RoR vs a lighter-weight framework like Sinatra is a more interesting question, but it's about what you need out of the box.

Server-side JS is fine, and actually very nice in some contexts. The language and runtime(s) have come a long way.

But anyone who tries it without really understanding JS is eventually going to have a bad time. It’s important to know how to work with the event loop, how to properly use promises, etc. Server-side JS is a lot more unforgiving than front-end JS when it comes to these concepts.
