It's simple these days, you can never go wrong with Javascript, you can use it both frontend and backend, it's a safe bet.
Once you've mastered that you could pick up one other language e.g. a typical backend language like Python, PHP, Go, Rust etcetera. But I would say it isn't even strictly necessary.
Or if you want to expand your horizon beyond OO then try to pick up a functional programming (FP) language like Haskell, Clojure or Elixir, if you're in for an intellectual challenge.
Another option would be Flutter, if you're interested in mobile development.
But yeah, Javascript (maybe coupled with Typescript) is a no-brainer these days.
