Access Javascript modules from a C++ module in node.js

I routinely access compiled c++ modules in js modules by passing in the module name as an argument when creating the other module, like so:

var cppModule = require('./cppModule');
var cppModObject = new cppModule.SomeObject;
var jsModule = require('./jsModule');
var jsModObject = new jsModule.OtherObject(cppModObject);

And in my js I have something like:

var jsModule = function(otherModArg) {
  var otherModuleObject = otherModArg;
  ...
}

My question is whether I can do the reverse, i.e. pass in some instantiated js object into my c++ module and access that object within the c++. I'm happy to post more code if it would be helpful...I haven't been able to find any doc on this yet. Thanks!
