Repl.it has expanded its programming language support by introducing Clojure, a Lisp dialect known for its emphasis on immutability, which operates on the Java Virtual Machine. This addition follows the recent introduction of Haskell support and reflects Repl.it's ongoing commitment to incorporating more functional languages. The Clojure implementation is based on the NRepl server, ensuring users experience the expected native behavior of a Clojure REPL. Users are encouraged to explore this new offering at repl.it/languages/clojure and provide feedback for further enhancements.
