Does deleting a property before replacing it change garbage collecting priority?

If you are replacing a property on an object that is a reference to a giant object, does it ever make sense to delete that property before replacing it?

const a = {
  child: b //Reference to big object
delete a.child;
a.child = c; //Another big object


const a = {
  child: b //Reference to big object
a.child = c; //Another big object
