Object-oriented programming (OOP)

Object-oriented programming (OOP) is a programming paradigm based on the concept of objects fundamental to many programming languages, including Java and C++. OOP can be devided in two sub types: class-based (or “classical”) and prototype-based OOP (found in JavaScript, for example).

Object-oriented programming has several advantages over procedural programming:
