Scheme
A dialect of the Lisp family of Programming Language. A Lisp-1 with a single symbol namespace. Various version of Scheme have been published as a series of academic publications starting in 1975. Features include lexical scope, guaranteed tail-call optimization, and lazy evaluation. Generally known for being very minimalist.

- Scheme
Scheme is a classic programming language in the Lisp family. It emphasizes functional programming and domain-specific languages but adapts to other styles. Known for its clean and minimalist design, Scheme is one of the longest-lived and best-studied dynamic languages, and has many fast and portable implementations.
From the Scheme standard reports:
Programming languages should be designed not by piling feature on top of feature, but by removing the weaknesses and restrictions that make additional features appear necessary. Scheme demonstrates that a very small number of rules for forming expressions, with no restrictions on how they are composed, suffice to form a practical and efficient programming language that is flexible enough to support most of the major programming paradigms in use today.** What's new in Scheme

If you have programmed before but are new to Scheme, you should
to get to know the language better.
The first pane, the REPL, is where the user interacts with the interpreter. The REPL is an ideal place to try out code snippets and debug code.
The second pane is the editor area. It allows creating and editing files that are local to the browser and accessible to Scheme code as files in the root directory, i.e. "
/". The files will persist in the browser between sessions. Use the "+" tab in the editor area to create new files and open existing files.

Scheme is a dialect of the Lisp family of programming languages. Scheme was created during the 1970s at the MIT Computer Science and Artificial Intelligence Laboratory (MIT CSAIL) and released by its developers, Guy L. Steele and Gerald Jay Sussman, via a series of memos now known as the Lambda Papers. It was the first dialect of Lisp to choose lexical scope and the first to require implementations to perform tail-call optimization, giving stronger support for functional programming and associated techniques such as recursive algorithms. It was also one of the first programming languages to support first-class continuations. It had a significant influence on the effort that led to the development of Common Lisp.
The Scheme language is standardized in the official Institute of Electrical and Electronics Engineers (IEEE) standard and a de facto standard called the Revisedn Report on the Algorithmic Language Scheme (R/n/RS). A widely implemented standard is R5RS (1998). The most recently ratified standard of Scheme is "R7RS-small" (2013). The more expansive and modular R6RS was ratified in 2007. Both trace their descent from R5RS; the timeline below reflects the chronological order of ratification.
