How to define a Class in Javascript

First of all, There is no such thing as a Class in Javascript. It’s all objects. Hence use functions and literals to simulate “Class”y development.

 
//Way 1: Function simulating class. 
function Phone(model){    
    this.model = model; 
} 
myPhone = new Phone("Android");  

//Way 2: literal as singleton 
var Phone = {
    model: 'Android' 
};  

//Way 3: Singleton into function 
var Phone  = new function(){     
    this.model = "Android" 
}
