Scheme is a programming language that is designed for teaching students how to program. Scheme is a very small and simple language, which makes it easy to learn. Scheme programs are also easy to read and understand.

Scheme is a functional language, which means that programs are composed of functions. Functions are written in a nested style, with the most important functions at the top. In Scheme, functions are first-class objects, which means that they can be passed as arguments to other functions, and returned from functions.

Scheme is a dynamically typed language, which means that the type of a variable is not fixed. This makes Scheme programs more flexible, but also more error-prone.

Scheme has a very simple syntax, which makes it easy to learn. The language also has a number of built-in functions, which makes it easy to get started writing programs.

Scheme is a popular language for teaching students how to program. It is also used in many research projects.

Scheme programming features

Scheme is a statically scoped and statically typed programming language with a simple, consistent semantics. It is a functional programming language and a member of the Lisp family.

  • Scheme was designed to have a minimal core with powerful extensions, and many Scheme implementations provide a large number of extensions. Scheme is used as a scripting language, a teaching language, and a tool for writing programs, particularlygraphical user interfaces and network programs.
  • Scheme has been used to write several large programs, including the graphics program X Windows and the window manager Enlightenment.
  • Scheme is an interpreted language, as opposed to a compiled language. Scheme programs are typically run in a Scheme interpreter, which reads Scheme source code and produces an executable program.
  • Scheme programs are composed of expressions. An expression is a unit of code that produces a value. Scheme expressions are typically written in prefix notation.
