In computer programming, cons ( or ) is a fundamental function in most dialects of the Lisp programming language. cons constructs memory objects which hold two values or pointers to values. These objects are referred to as (cons) cells, conses, non-atomic s-expressions ("NATSes"), or (cons) pairs. In Lisp jargon, the expression "to cons x onto y" means to construct a new object with (cons ''x'' ''y''). The resulting pair has a left half, referred to as the car (the first element, or content of address register), and a right half (the second element, or content of decrement register), referred to as the cdr.
It is loosely related to the object-oriented notion of a constructor, which creates a new object given arguments, and more closely related to the constructor function of an algebraic data type system.
The word "cons" and expressions like "to cons onto" are also part of a more general functional programming jargon. Sometimes operators that have a similar purpose, especially in the context of list processing, are pronounced "cons". (A good example is the :: operator in ML, Scala, F# and Elm or the : operator in Haskell, which adds an element to the beginning of a list.)
