LISP (historically LISP) is a family of programming languages with a long history and a distinctive, fully parenthesized prefix notation.[3] Originally specified in 1958, Lisp is the second-oldest high-level programming language. Only Fortran is older, by one year.[4][5] Lisp has changed since its early days, and many dialects have existed over its history. Today, the best-known general-purpose Lisp dialects are Racket, Common Lisp, Scheme, and Clojure.
