JavaScript Namespace Declaration

Question

I created a javascript class as follow:

var MyClass = (function() {
   function myprivate(param) {
      console.log(param);
   }

   return {
      MyPublic

Automating namespaces declaration in javascript is very simple as you can see:

var namespace = function(str, root) {
    var chunks = str.split('.');
    if(!root)
        root = window;
    var current = root;
    for(var i = 0; i < chunks.length; i++) {
        if (!current.hasOwnProperty(chunks[i]))
            current[chunks[i]] = {};
        current = current[chunks[i]];
    }
    return current;
};

// ----- USAGE ------

namespace('ivar.util.array');

ivar.util.array.foo = 'bar';
alert(ivar.util.array.foo);

namespace('string', ivar.util);

ivar.util.string.foo = 'baz';
alert(ivar.util.string.foo);
