A simple demonstration of classes in es6

Person.js

//
// Person.js
//
// This is a simple Person class.
// 
// It doesn't do much, but it demonstrates the use of ES6 classes. Note that
// this code will most likely not work in old browsers directly. To 'compile'
// this down to the more widely accepted ES5, you could use Babel.
//

class Person {
  constructor(name) {
    this.name = name;
  }

  say(text) {
    console.log(`${this.name} says: ${text}`);
  }
}

const bob = new Person('Bob');
bob.say("Hello World");
