Statically and dynamically scoped Lisp dialect developed by a loose formation of industrial and academic Lisp users and developers across Europe; the standardizers intended to create a new Lisp "less encumbered by the past" (compared to Common Lisp), and not so minimalist as Scheme, and to integrate the object-oriented programming paradigm well ...
In JavaScript, PHP, VBScript and a few other dynamically typed languages, the standard equality operator follows so-called loose typing, that is it evaluates to true even if two values are not equal and are of incompatible types, but can be coerced to each other by some set of language-specific rules, making the number 4 compare equal to the ...
The loop macro in ANSI Common Lisp is anaphoric in binding, where the it expression refers to the result of the test expression in a clause. [2] [3]Here is an example that sums the value of non-nil elements, where it refers to the values of elements that do not equal nil:
eq – given two expressions returns True if their values are equal; False if not if – given three expressions returns the value of the second if the value of the first is True, otherwise returns the value of the third lambda – given an argument list and an expression, returns them as a function
Lisp (historically LISP, an abbreviation of "list processing") is a family of programming languages with a long history and a distinctive, fully parenthesized prefix notation. [3] Originally specified in the late 1950s, it is the second-oldest high-level programming language still in common use, after Fortran.

Many Common Lisp types have a corresponding class. There is more potential use of CLOS for Common Lisp. The specification does not say whether conditions are implemented with CLOS. Pathnames and streams could be implemented with CLOS. These further usage possibilities of CLOS for ANSI Common Lisp are not part of the standard.
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.
