Not OP, but TS (as in TypeScript, right?) is not even in the same universe as Elixir with Phoenix when it comes to building backend services.

It's a very productive and readable programming language with excellent documentation and conventions, and the most ergonomic way of handling concurrent operations (thanks BEAM) I've encountered.

The VM it runs on was originally designed for telephone switches, which, it turns out, cleanly translates to the internet/http era.

It makes it trivial to do soft-realtime because it's just actors (GenServers) passing messages.

I invite you (and others) to try it out and do a small weekend project. It'll make you reconsider reaching for TS on the backend :)
