2.Object-Oriented Programming (OOP)

Explanation

  • It's a programming style; it defines how to organise your application
  • In OOP each program would be split up into self-contained objects, that then communicate with each other
  • Each object represents a part of the application: it contains its own data and logic
  • OOP is meant to make thinking about your applications easier, by having each object represent a real-life entity (i.e. Users, Profiles, Products)
