Revealing module pattern

DOJ.js

if (typeof DOJ == 'undefined') {
  DOJ = {};
}


// http://toddmotto.com/mastering-the-module-pattern/
DOJ = function () {
    var _myPrivateVar = "_myPrivateVar can be accessed only from within DOJ.";
    var myPublicProperty = "myPublicProperty is accessible as DOJ.myPublicProperty.";

    var _myPrivateMethod = function () {
        console.log("_myPrivateMethod can be accessed only from within DOJ.");
        return "Returned from _myPrivateMethod";
    };

    var myPublicMethod = function () {
        console.log("myPublicMethod is accessible as DOJ.myPublicMethod.");

        //Within myProject, I can access "private" vars and methods:
        console.log(_myPrivateVar);
        console.log(_myPrivateMethod());

        //The native scope of myPublicMethod is DOJ; we can
        //access public members using "this":
        console.log(this.myPublicProperty);
    };

    // return public properties and methods
    return  {
        myPublicProperty: myPublicProperty,
        myPublicMethod: myPublicMethod
    };
}();
