Functional programming is the programming technique that accentuates the functional factors required for creating and implementing the programs. OOP or the Object-Oriented Programs are the conceptual programming techniques that uses objects as the key. The programming model used in functional programming is a declarative programming model, while object-oriented programming uses the imperative programming model. In functional programs, variables and functions are the main elements of the code, while in object-oriented programs, objects and methods are the key elements. Functional Programming Functional programming also supports the programming languages like Lisp, Clojure, Wolfram, Erlang, Haskell, F#, R, and other prominent and domain-specific languages. Functional programming is a great fit for data science work, and R is the popular language among data scientists. FP languages can be translated well into an interactive environment, which makes the understanding of code easier. Functi...
