The Racket language is a modern dialect of Lisp and a descendant of Scheme. It is designed as a platform for programming language design and implementation. [9] In addition to the core Racket language, Racket is also used to refer to the family of programming languages [10] and set of tools supporting development on and with Racket. [11]

Mostly based on Scheme and Common Lisp, was designed as system and application programming language by Apple; first used to write an operating system and applications for internal prototypes of the later released Apple Newton computer; first official version of Apple Dylan also had s-expression based syntax; Apple collaborated with partners to ...
After having declined somewhat in the 1990s, Lisp has experienced a resurgence of interest after 2000. Most new activity has been focused around implementations of Common Lisp, Scheme, Emacs Lisp, Clojure, and Racket, and includes development of new portable libraries and applications.
[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 Common Lisp, Scheme, Racket, and Clojure.[6][7][8] Lisp was originally created as a practical mathematical notation for computer programs, influenced by (though
Like all implementations in the Scheme family, Racket implements full tail call elimination. Racket takes this further: the language is made fully safe-for-space, via live variable analysis. This complements the precise garbage collector and in some cases, like in the implementation of Lazy Racket, the two features are crucial for proper execution.
Scheme was the first dialect of Lisp to choose lexical scope. It was also one of the first programming languages after Reynold's Definitional Language [ 15 ] to support first-class continuations . It had a large impact on the effort that led to the development of its sister-language, Common Lisp , to which Guy Steele was a contributor.
