Functional programming is a programming paradigm that focuses on creating software applications by composing pure functions that avoid changing state and mutating data. In functional programming, functions are treated as first-class citizens and can be passed around like any other value, including being returned from other functions.

Functional programming differs from imperative programming in that the latter focuses on describing how the program should be executed step-by-step, often relying on loops, conditionals, and mutable variables. Imperative programming is based on the idea of commands that modify the state of the program, and the execution of these commands often happens in a specific order.

Object-oriented programming (OOP), on the other hand, is a programming paradigm that focuses on objects and their interactions. In OOP, objects encapsulate data and behavior, and communication between objects is done through method calls. OOP emphasizes the use of inheritance, encapsulation, and polymorphism.

In functional programming, the focus is on composing functions that transform data without mutating it, while in OOP, the focus is on creating objects that encapsulate data and behavior. Functional programming encourages immutability and avoids side effects, while OOP emphasizes encapsulation and abstraction.

Both functional programming and OOP can be used to write high-quality software…
