Clojure
ELI5 — The Vibe Check
Clojure is Lisp that actually got a real job. It lives on the JVM, loves immutable data, and uses more parentheses than a passive-aggressive text message. Once you get it, you'll never want mutable state again.
Real Talk
A modern, dynamic, functional Lisp dialect that runs on the JVM (and JavaScript via ClojureScript). Clojure emphasizes immutability, persistent data structures, and a simple concurrency model through atoms, refs, and agents.
Show Me The Code
(defn greet [name]
(str "Hello, " name "!"))
(->> (range 10)
(filter even?)
(map #(* % 2)))
;; => (0 4 8 12 16)
When You'll Hear This
"Clojure's REPL-driven development is the best workflow I've ever experienced." / "The parens scared me at first, but after a week of Clojure I couldn't go back."
