- Functional Programming
In computer science, functional programming is a programming paradigm—a style of building the structure and elements of computer
programs—that treats computation as the evaluation of mathematical functions and avoids changing-state and mutable data. It is a
declarative programming paradigm in that programming is done with expressions or declarations instead of statements. In functional code,
the output value of a function depends only on its arguments, so calling a function with the same value for an argument always produces
the same result. This is in contrast to imperative programming where, in addition to a function's arguments, global program state can
affect a function's resulting value. One of the key motivations for the development of functional programming is making a program easier
to understand by eliminating changes in state that do not depend on function inputs which are called side effects.
