"Functional" is a term used in various contexts, but the most common meanings are:
1. In Programming:
* Functional programming is a programming paradigm where programs are constructed by composing pure functions. This means functions have no side effects (they don't change anything outside their scope) and always produce the same output for the same input.
* Functional languages are programming languages that support functional programming. Examples include Haskell, Lisp, and F#.
* A functional component in a user interface (UI) library like React is a self-contained piece of code that only renders output based on its input properties.
2. In General:
* Functional can mean something that serves a specific purpose or function. For example, "a functional kitchen" means a kitchen that is well-equipped and serves its purpose effectively.
* In a medical context, "functional" can describe something that is working normally. For example, "functional mobility" refers to the ability to move around without limitations.
