Prototype chains

prototype_chains.js

var obj = {
  prop: 1
};

console.log(obj.prop); // logs 1
console.log(obj.prop2); // logs undefined

// If you want to delegate failed lookups to the prototype 
// you use this technique
var obj2 = Object.create(obj); // this way the newly created object has access to the obj properties!!!

console.log(obj2.prop); // logs 1
