In computer science, functional programming is a programming paradigm, a style of building the structure and elements of computer programs, that emphasizes functions that produce results that depend only on their inputs and not on the program mutable state-i.e. pure mathematical functions.
Functional programming is a programming paradigm. This is in computer science. A programming paradigm is a style of building the structure and elements of computer programs. A programming paradigm of building the structure and elements of computer programs emphasizes functions. These functions produce results-i.e. pure mathematical functions. These results depend only on their inputs and not on the program mutable state. A programming paradigm is a style.
