(function($, rootspace){
  window[rootspace] = function(namespace, object){
    var setNamespace = function(namespace){
      var root = window[rootspace];
      $(namespace.split(".")).each(function(idx, name){
        root = root[name] = root[name] || {};
      });
      return root;
    };
    return $.extend(true, setNamespace(namespace), object);
  };
})(jQuery, "APP");

fcuk php - the link works without it as-well http://www.opensource.org/licenses/mit-license ;)

Usage example:

APP("some.name.space", {
  init: function() {
    // function body
  }
);
// this would create name-spaced function available under:
APP.some.name.space.init();
