Detailed explanation-1: -Functional programming is based on mathematical functions. Some of the popular functional programming languages include: Lisp, Python, Erlang, Haskell, Clojure, etc. Functional programming languages are categorized into two groups, i.e. −

Detailed explanation-2: -In functional programming, functions are treated as first-class citizens, meaning that they can be bound to names (including local identifiers), passed as arguments, and returned from other functions, just as any other data type can.

Detailed explanation-3: -Functional programming is a declarative programming paradigm, where programs are written as mathematical functions whose order of execution is not solely defined by the programmer. These mathematical functions produce consistent outputs solely dependent on the inputs.

Detailed explanation-4: -Functional programming is a programming paradigm in which we try to bind everything in pure mathematical functions style. It is a declarative type of programming style. Its main focus is on “what to solve” in contrast to an imperative style where the main focus is “how to solve”.

Detailed explanation-5: -Functional programming is a form of declarative programming. In contrast, most mainstream languages, including object-oriented programming (OOP) languages such as C#, Visual Basic, C++, and Java, were designed to primarily support imperative (procedural) programming.
