Applicative programming language
open-in-new
<p>In the <a href="/facts/Programming_paradigm/7LwgRpB3">classification of programming languages</a>, an applicative programming language is built out of <a href="/facts/Function_(computer_science)/9vFJrg0A">functions</a> applied to <a href="/facts/Argument_(computer_science)/LcuLbbSq">arguments</a>. Applicative languages are <a href="/facts/Functional_programming/cdxqPEIM">functional</a>, and applicative is often used as a synonym for functional. However, <a href="/facts/Concatenative_languages/aGKqUHWj">concatenative languages</a> can be functional, while not being applicative. </p><p>The <a href="/facts/Semantics_(computer_science)/JEP1zyBv">semantics</a> of applicative languages are based on <a href="/facts/Beta_reduction/DaD3RuQ4">beta reduction</a> of terms, and <a href="/facts/Side_effect_(computer_science)/AU3GlLzG">Side effect</a> such as mutation of <a href="/facts/State_(computer_science)/4Yu8xXHS">state</a> are not permitted. </p><p><a href="/facts/Lisp_programming_language/xJHA3CrX">Lisp</a> and <a href="/facts/ML_programming_language/RfwxASRF">ML</a> are applicative programming languages. </p>
