Getting an Array of Property Values Using Underscore

Question

I'd like to extend each object in the array of objects below with an array of value* as seen below:

array = [object, object, object]

object = {key: array2, key2: value, key3: value}

array2 = [object2, object2]

object2 = {key: object3, key2: child, key3: object4}

object4 = {key: value, key2: value, key3: value*}

How do I write an underscore operation to extend the objects in the original array to include an array of value* as illustrated above?

It is possible using double _.each as a wrapper

_.each( array, function( item /* object */ )
{
    _.each( item.key /* array2 */, function( item /* object2 */ )
    {
        _.extend( item.key3 /* object4 */, {key3:5} )
    })
});

I tried that but it did not bring the last key value pair to the front like I hoped. I've almost found it now and will publish my answer soon.

Actually I can't publish it because I changed my data structures so much to accomodate the change I was looking for that it no longer relates to the question . . .
