Constructor pattern and Object.create pattern effects on __proto__

Premise: I'm try to abbandon constructor pattern

As you can see in looking at console.log() here

//Constructor pattern
function F(){}

F.prototype.foo = null;

console.log(new F());

//Object create pattern
var FPrototype = {};

FPrototype.foo = null;

console.log(Object.create(FPrototype))

the object created by Object.create API has the __proto__ properties referencing the prototype as Object while the one created by constructor has the __proto__ prop referencing the prototype as the name of the constructor function.

I suppose that this behaviour is trying to simulate the strong typed langs, assuming that your constructor defines a new type identified by the constructor name itself.

That said, when my prototype chain grows I find very useful to identify different prototypes by name/"type", so is there any way to correctly have this using Object.create instead of constructor?
