Emacs Lisp. Emacs Lisp is a dialect of the Lisp programming language used as a scripting language by Emacs (a text editor family most commonly associated with GNU Emacs and XEmacs). It is used for implementing most of the editing functionality built into Emacs, the remainder being written in C (as is the Lisp interpreter itself).
Scheme is primarily a functional programming language. It shares many characteristics with other members of the Lisp programming language family. Scheme's very simple syntax is based on s-expressions, parenthesized lists in which a prefix operator is followed by its arguments.s in other Lisps, the term  thunk  is used in Scheme to refer to a procedure with no arguments. The term proper tail recursion refers to the property of all Scheme implementations, that they perform tail-call optimization so as to support an indefinite number of active tail calls.
