What is Lisp?
Lisp is the second-oldest high-level programming language. It is a dynamic and strongly typed programming language developed by Steve Russell, Timothy P. Hart, and Mike Levin in 1958.
Only Fortran is older, by one year. The commonly used general-purpose Lisp dialects are Clojure, Common, and Scheme.
Lisp was designed as a mathematical notation for machine programs, supported by Alonzo Church's lambda calculus model, and quickly became the favored programming language for artificial intelligence (AI) research. Moreover, Lisp pioneered in IT, including tree data arrays, predefined storage management, dynamic coding, higher-order functions, repetitions, self-hosting compiler, and read–eval–print loop.
