Scheme is a functional programming language in the Lisp family, closely modelled on lambda calculus with eager (applicative-order) evaluation.

Scheme is a functional programming language. It is designed to provide a mathematically well-founded language based on lambda calculus (with eager evaluation).

It follows a minimalist design philosophy specifying a small standard core with powerful tools for language extension. Its compactness and elegance have made it popular with educators, language designers, programmers, implementors, and hobbyists.

The Scheme language belongs to the Lisp Family. Since Scheme uses a single namespace for naming functions and other values, it is called a lisp-1.
