oop in javascript.js

var human = {
   species: "human",
   create: function(values) {
      var instance = Object.create(this);
      Object.keys(values).forEach(function(key) {
         instance[key] = values[key];
      });
      return instance;
   },
   saySpecies: function() {
      console.log(this.species);
   },
   sayName: function() {
      console.log(this.name);
   }
};

// Musician extends Human, so it inherits all the methods and properties
var musician = human.create({
   species: "musician",
   playInstrument: function() {
      console.log("plays " + this.instrument);
   }
});

// Let's create John
var john = musician.create({
  name: "John",
  instrument: "drums"
});

john.playInstrument(); // plays drums
john.sayName(); // john
