Clojure - paradigm shift and leverage. Rust - speed and safety.

For frontend, I would say Svelte and Sapper.

  Rust       - for low-level / systems programming
  Elixir/OTP - for distributed systems, backend, JS-less 
  frontend (Phoenix LiveView)
  Elm        - for SPAs (Single Page Apps)
  Julia      - for number crunching
  kdb+/q     - for timeseries-specific workloads 
  Solidity   - for get-rich-quick scams
  NetLogo    - for agent-based simulations

  Typescript - for legacy browser, ReactNative and node.js code
  Kotlin     - for Android
  Swift      - for iOS and other Apple OSes

F# and .Net Core

And upon searching/reading: Giraffe framework.

I ran the hello world program on my 6-core MacBook and it got ~100 req/s. That was with SSL so enabling keepalive gets ~50k req/s (with P98 <1ms, P99 1ms, max 176 ms) on a Debug build though I don't expect much difference for a Release one.
