  kellysDog = new Dog('same, 'richback');
  
  console.log(kellysDog.name); => will print 'Sam'

• prototypical oriented programming: don't have to create a new instance, can create new on the fly - can customize anything and add on

  a = [1,2,3,4]
  
  Array.prototype.first = function  {
        return this[o];
  }
  
  console.log(a.first());
