Javascript OOP - Example

oop1.js

var foo = function(){};

foo.prototype.bar = (function() {
  return 'Test';
});
 
var obj = new foo();

console.log(obj.bar());

oop2.js

var foo = (function(){

  this.bar = (function() {  
    return 'bar';
  });

});

var obj = new foo();

console.log(obj.bar());

oop3.js

var obj = {};
 
Object.defineProperty(obj, "foo", {
    value: "foo",
    writable: true,
    enumerable: true,
    configurable: true
});
 
console.log(obj.foo);

oop4.js

var obj = {};
 
Object.defineProperties(obj, {
  "foo": {
    value: "foo",
    writable: true,
    enumerable: true,
    configurable: true
  },
  "bar":{
    value: "bar",
    writable: true,
    enumerable: true,
    configurable: true
  }
});

console.log( obj.foo );
console.log( obj.bar );

oop5.js

var foo = function(){};
var bar = new foo();
console.log(bar);

var foo = {};
console.log(foo);

var foo = Object.create(null);
console.log(foo);

oop6.js

Foo = {};

(function (bar) {
    bar.consoleBar = function(){
       return ('Jhon Doe');
    };
})(Foo);

console.log(Foo.consoleBar());
