Lisp dialects are variations of the original Lisp programming language, which was developed in the late 1950s. Over the years, many dialects have emerged, each with unique features and purposes. Some of the most well-known dialects include Common Lisp, Scheme, and Clojure. These dialects maintain the core principles of Lisp, such as symbolic expression and functional programming, while introducing their own syntax and libraries. Each dialect serves different communities and applications. For instance, Scheme is often used in academic settings for teaching programming concepts, while Clojure is designed for concurrent programming on the JVM. Despite their differences, all Lisp dialects share a common heritage and emphasize code as data, allowing for powerful metaprogramming capabilities.
