ways to create objects in js

gistfile1.js

// object literal notation
var eugene = {
  name : 'eugene',
  age : 22,
  meow: function () {
    console.log("meow");
  }
};

console.log(eugene);
eugene.meow();

// object constructor notation
var eugene = new Object();
eugene.name = 'eugene';
eugene.age = 22;
eugene.meow = function () {
  console.log('meow');
};

console.log(eugene);
eugene.meow();

// object constructor function
  // this is not an object, it's a function which produces objects
function Person (name, age) {
  this.name = name;
  this.age = age;
}

Person.prototype.meow = function () {
  console.log('meow');
};

var eugene = new Person('eugene', 22); // here we use our object constructor function to construct a new object
console.log(eugene);
eugene.meow();
