Java Script
What is OOPS in Java Script? The two important principles with OOPS in java-script are Object Creation patterns(Encapsulation) and Code Reuse Patterns(Inheritance). How to use in class? Javascript does not contain class statement. Javascript is a prototype based language. Javascript uses functions as classes. Defining a class is easy as defining a function.In the example below we define a new class called as Car. function Car() { } var car1=new Car(); var car2=new Car(); For creating instances of any class i.e. objects use new keyword.In the above snippet we have created 2 instances of object class.
