Functional Programming

Functional programming is a programming paradigm that treats computation as the evaluation of mathematical functions and avoids state and mutable data. It is a declarative programming style, which means programming is done with expressions or declarations instead of statements.

What is Functional Programming?

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, which means programming is done with expressions or declarations instead of statements. Functional code is composed of expressions that each return a value, rather than a sequence of commands that change state. This is in contrast to imperative programming, which uses commands for control flow that change program state.

The Benefits of Functional Programming

Functional programming is a programming paradigm that emphasizes the evaluation of functions. It is a declarative programming style, which means programming is done with expressions or declarations instead of statements. Functional programming is a very concise and elegant way of programming that can lead to more reliable and maintainable code.

Functional Programming Languages

Functional programming languages are a type of programming language that allows for more efficient coding by breaking a program down into small, reusable pieces of code called functions. These functions can be reused in other programs, making functional programming languages very versatile. Some of the most popular functional programming languages include Lisp, Scheme, and Haskell.

Learning Functional Programming

Functional programming is a programming paradigm that treats computation as the evaluation of mathematical functions and avoids state and mutable data. It is a declarative programming style, which means programming is done with expressions or declarations instead of statements. Functional programming has its roots in lambda calculus, a formal system developed in the 1930s to investigate function definition, function application, and recursion. Functional programming languages can be used to write programs in a declarative style.
