Question

According to this article it should be a Javascript 2.0 way to define class. However, I never saw that in practice. Thus the question. How to use class keyword and what is the difference between Javascript 1.x way of doing things?

Answer 1

I know this is a old post, but as of today i.e with the advent of ECMAScript 6 we can declare javascript classes.

The syntax goes as follows :

class Person{
  constructor(name){
    this.name = name;
  }
  printName(){
    console.log('Name is '+this.name);
  }
}
var john = new Person('John Doe');
john.printName(); // This prints 'Name is John Doe'
