So you're using a weird language
I think it's getting harder and harder to justify using anything but the most popular languages and frameworks.<p>You need a VERY good reason to use anything except TypeScript/C#/Java/Golang/Python/React/Vue/Postgres/MySQL/SQL server/Oracle.  Perhaps Rust. These technologies are good enough to get almost anything done these days.  There's exceptions of course for example games tend to written in C++ and embedded is often C.<p>Apart from anything, you should be using these most popular technologies if only for the sake of recruiting.<p>Using less popular technologies like Erlang/Dart/Kotlin/Ruby/Elixir/OCaml/F# or whatever weird new JavaScript React alternative thing got you interested lately is a bad idea not just for recruiting but for support and community and documentation.<p>If you are the person deciding which technologies to use, you should probably be using the most mainstream thing you can, not the coolest newest thing that you read on Hacker News.  There's any number of companies saddled with their main systems being built in the weird assed framework that the fourth-to-last CTO decided was a good idea, and those companies are now stuck with the problem.<p>I should note of course that my comments refer to company/organisation development.  For personal projects or fun or whatever you should do whatever the heck you enjoy.
