JavaScript Inheritance via Prototypes and Closures | ruzee.com - Steffen Rusitschka
Prototype-based

var A = function(){}; // This is the constructor of "A"
A.prototype.value = 1;
A.prototype.test = function() { alert(this.value); }
var a = new A(); // create an instance of A
alert(a.value);  // => 1
alert(a.test()); // => 1

Closure-based

var C = function() {
  // a private function
  var print = function(msg) {
    alert(msg);
  };
  this.value = 1;
  this.test = function() {
    print(this.value);  // calls our private function
  };
};
var c = new C();
alert(c.value); // => 1
alert(c.test()); // => 1
