What is an Object Oriented Programming in 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 with 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.

Objects are composed of attributes. If an attribute contains a function, it is considered to be a method of the object, otherwise, the attribute is considered a property.
