About JavaScript

JavaScript is an Object Oriented Programming (OOP) language. A programming language can be called object-oriented if it provides four basic capabilities to developers −
  • Encapsulation − the capability to store related information, whether data or methods, together in an object.
  • Aggregation − the capability to store one object inside another object.
  • Inheritance − the capability of a class to rely upon another class (or number of classes) for some of its properties and methods.
  • Polymorphism − the capability to write one function or method that works in a variety of different ways.
