Object-oriented programming (OOP) is a programming paradigm based on the concept of objects fundamental to many programming languages, includingJava andC++. OOP can be devided in two sub types: class-based (or "classical") and prototype-based OOP (found inJavaScript, for example).

Object-oriented programming has several advantages over procedural programming:

• OOP provides a clear structure for the programs

• OOP helps to keep the code DRY "Don't Repeat Yourself", and makes the code easier to maintain, modify and debug

• Logic can be abstracted, encapsulated, composed, inherited and decoupled
