3. OOPs CONCEPTS
● Class
● Object
● Inheritence
● Encapsulation
● Abstraction
● Polymorphism
Everything related to object & its attributes.

4. CLASS
A template defining an object properties and method.

5. OBJECT
An object represent an entity with data and methods. A keyword
'new' is used to create an object of a class.

6. INHERITENCE
Creating a new version of a class is inheritence. The new class is
callled child class and other is parent class.

7. INHERITENCE ON SINGLE

8. ENCAPSULATION
Wrapping up of data & methods of a class & its parent classes into
a single unit is called encapsulation.
In the previous example, Square does not need to know how the
Rectangle class's calculateArea() method is implemented, but still
can use that method; the Square class doesn't need to explicitly
define that method unless we want to change it.

9. ABSTRACTION
Abstraction is a technique for managing complexity. Its the way we
hide the methods & properties from child class.
Square class does not need to know about calculateArea method
of Rectangle class, its absractions.

10. POLYMORPHISM
Just as all methods and properties are defined inside the prototype
property, different classes can define methods with the same
name.
