Most companies have sets of supported languages and you need to use the right tool for the job. For small one-off tasks or simple services, your company should have a template for writing those in a good scripting language: Python, Ruby .. something you can write tests/specs for if it grows, that has a good amount of programmers you can hire, etc. Your core service apps might be written in something different, that can scale up, whether that's a JVM lang (Java/Scala/Clojure/Kotlin) or a .NET (C#/VB.Net) or Elixir or Rust or whatever depends on a lot of things. You want to have something your core programmers enjoy writing in, but also something you can find new people for as your company expands. It can be a delicate balance. You can have multiple core languages (my current company is Node/React for most front end, React Native for apps, Clojure for almost all backend, some .NET and Python/Go/Terraform for all devops). It's best to have a core tech stack with some choice than just let every team do anything in whatever. But of course, it's dependent on your company and market. Your mileage will vary.
