What is Racket?
Racket is the new name for PLT Scheme, an everyday programming language known for a strong macro system as well as flexibility. Its origins are academic, and its use in the study of programming languages throughout the years can be seen in several of its features: for instance, its ability to handle implementation of a wide range of projects as well as the ease with which it can be adjusted for new dialects or languages. Some of the languages for whose creation it has played a part would be ProfessorJ, Lazy Scheme, ACL2, and FrTime. Users can also access 3rd-party libraries with Racket if they wish, due to the bundled PLaneT manager.
The Integrated Development Environment used when programming with Racket is the self-hosted DrRacket, which comes with its own debugging tool, source highlighting features for checking errors, algebraic stepping, and more. It is available for multiple operating systems and has long been used in conjunction with Racket in order to provide students of programming and computer technology an introduction to scripting using the Scheme language (from which Racket descends). The environment also comes with a Help data bank.
