Racket is a programming language that is part of the Lisp family, designed for general-purpose programming and teaching computer science concepts. It emphasizes functional programming and supports a variety of programming paradigms, including procedural and object-oriented styles. Racket is known for its powerful macro system, which allows developers to create new syntactic constructs easily. In addition to being a programming language, Racket also serves as a platform for language creation. Users can design their own programming languages tailored to specific tasks or educational purposes. This flexibility makes Racket popular in academic settings, particularly in courses related to computer science and programming languages.
