=== [[/Functional Programming/]] ===

Functional programming is a programming paradigm that emphasises the use of pure functions, immutable data, and the avoidance of side effects. In functional programming, programs are constructed by composing functions that transform data rather than by changing state. It promotes a declarative and mathematical approach to problem-solving, focusing on what needs to be computed rather than how. Key concepts in functional programming include higher-order functions, recursion, immutability, and the use of functional data structures. Functional programming languages, such as Haskell and Clojure, provide powerful tools and abstractions for expressing complex computations concisely and reliably. By emphasising immutability and pure functions, functional programming enables developers to write code that is easier to reason about, test, and parallelise.
