I use it for everything.

Professionally, I write backend services (mix of micro-services and bigger SOA ones) of various types. Some command lines, some scripts, a few web apps.

In my spare time I use it for random things, mostly stuff I mess on, personal scripts, doing programming challenges, websites, data exploration, etc.

You can use Clojure with NodeJS as well using ClojureScript by the way, or NBB if you want something more straightforward for writing NodeJS scripts.
