Self executing function as object property value in javascript

Is it possible to have a self executing function which is an objects property value assign values to other properties in the object?

e.g. - what I would like to do is this:

var b={
  c:'hi',
  d:null,
  e:new function(){this.d=5}
};

But the "this" inside the new function seems to refer to b.e. Is it possible to access the b.e parent (i.e. b) from inside the function?

This is how you do it.

Often called the module pattern (more info)

var b = function () {
   var c = 'hi';
   var d = null;

   return {
     c : c,
     d : d,
     e : function () {
       // this function can access the var d in the closure.
       d = 5;
     }
   }
}();

You can access the value within the function, you just need to get rid of the new, i.e.

e: function () {
    this.d = 5;
}
