What Is Functional Programming?

Functional Programming (also called FP) is a programming paradigm which is a style of building the structure and elements of computer software programs that treats computation as the assessment of mathematical functions and avoids changing state and mutable data. It is a declarative programming paradigm, that is to say, Programming is done with expressions or declarations instead of just using statements.

In Functional code, the output value of a function depends solely on its arguments, so calling a function with the same value for an argument would always give up the same result. This is in contrast to Imperative Programming where, in addition to a function's arguments, a global program state can affect a function's resulting value. Totally removing the side effects, that is, changes in state that do not depend on the function inputs can make understanding a Program easier, which is one of the key motivations for the development of Functional Programming.

Functional Programming's main focus is on “what to solve” which is the opposite of an Imperative style where the main focus is on “how to solve”. It uses expressions instead of statements. An expression is being run and evaluated to bring about value whereas a statement is executed to assign variables.

Functional Programming languages are specially created to manage symbolic computation and applications that depend on list Programming. Functional Programming is based on mathematical functions. Some of the popular functional programming languages include Python, Javascript, Haskell, Clojure, etc. 

Categories Of Functional Programming

Functional programming languages are categorized into two groups, which are:

1. Pure Functional Languages: These types of Functional languages only support Functional paradigms. Example Haskell.

2. Impure Functional Languages: These types of functional languages support Functional paradigms and also supports Imperative style of Programming. For example, LISP.

Features and Characteristics Of Functional Programming

There are a lot of features and Characteristics of Functional programming. below are some of its major Characteristics:

1. Functional programming languages are developed on the basics and concepts of mathematical functions that use conditional expressions and recursion to perform computation activities.

2. Functional programming also supports Higher-Order functions and lazy evaluation features.

3. Functional Programming languages don't support Control flow like loop statements and conditional statements such as If, Else and Switch Statements. They directly use the functions and functional calls  declared in the program

4. Just like in Object-Oriented Programming, Functional Programming languages also support popular concepts such as Abstraction, Encapsulation, Inheritance, and Polymorphism.

Benefits And Advantages of Functional Programming

Functional Programming offers a lot of advantages, below is some of them:

1. Bugs-Free Code: Functional Programming does not support state management, so there are absolutely no side-effects results and we can write error-free codes.

2. Efficient Parallel Programming: Functional Programming languages have NO Mutable state, so there are none of the regular state-change issues we see in some other kinds of programming. One program "Functions" is to work parallel as "instructions". Such codes support for easy reusability and testability.

3. Efficiency: Functional programs are made up of independent units that can run one after the other. As a result, such programs are more efficient.

4. Supports Nested Functions: Functional programming allows you to have Nested Functions in your project.

5. Lazy Evaluation: Functional programming supports Lazy Functional Constructs, for example, Lazy Lists, Lazy Maps, etc.
