Github NodeJS vs Ruby On Rails

Joy to the web

Joy is a web framework written in janet for people who like clojure syntax, fast startup time and very low memory usage.
(use joy)

(defn home [request]
  (text/plain "You found joy!"))

(def routes [[:get "/" home]])

(def handler (handler routes))

(server handler 8000)

Starts fast, stays fast

Joy starts up in milliseconds so you can get started (and restarted) without worrying about restarting the repl and waiting... a while

Low Memory Usage

Joy takes so little memory, you can run dozens (if not hundreds) of instances on a cheap virtual private server

Clojure-like

Joy is written with janet, a modern lisp with clojure-ish idioms, including data literals and immutable data structures
