#Scheme
Scheme is a programming language that was created in 1975 by Gerald Sussman and Guy Steele. It is an interpreted, dynamically typed dialect of Lisp that is used for scripting and other applications. The syntax of Scheme is minimalistic, making it easier to read and write programs compared to other languages. Scheme has strong support for functional programming, allowing developers to write code with fewer lines of code than many other languages require.
The main purpose of Scheme is to provide a platform for teaching computer science concepts such as recursion, data abstraction, higher-order functions (functions which take other functions as arguments) and macros (which are similar to C preprocessor directives). These concepts are demonstrated through the use of lambda expressions, closures and first class continuations (which allow you to save the state of a program at any point). There are also several libraries available for extending the language’s capabilities.
Due to its minimalistic syntax and powerful features, Scheme has become popular among academics who wish to teach their students advanced topics without introducing them too much complexity from traditional languages like Java or C++. In addition, several implementations have been released under open source licenses so anyone can modify the language however they see fit without having to worry about copyright issues or paying expensive licensing fees. This means that not only can you learn about these powerful concepts but you can make your own modifications if necessary!
