Test of adding child objects to a parent object.

This should allow defining process units in separate files, then adding them to parent processUnits object.

But does this leave child in memory too?

I can set it to null after putting into parent, but does JS garbage collection free memory?

See https://javascript.info/garbage-collection

------- SCRIPT -----------


        var myParent ={};



        var child01 = {name : 'joe', age : 10};

        var child02 = {name : 'ann', age : 12};



        myParent['child01'] = child01;

        myParent['child02'] = child02;



        // WARNING: have to use " around strings with ' below



        document.write("<br> child02['name'] = " + child02['name'] );

        document.write("<br> myParent['child02']['name'] = " + myParent['child02']['name'] );



        child02 = 0;

        document.write("<br> after zeroing child02, child02['name'] = " + child02['name'] );

        document.write("<br> after zeroing child02, myParent['child02']['name'] = " + myParent['child02']['name'] );
