If you have viewmodels with a sort of base class like

var baseViewModel=function(){
     var self=this;
     self.awesomeProperty=ko.observable("");

     return self;
};

and a concrete viewmodel that uses that base class like

var featurViewModel=function(){
        var self=baseViewModel();
        self.featureProperty=ko.observable("");

       return self;
}

the $root variable in of the knockout context is the global window object. Doing ko.toJS(context.$root) will crash
