assuming have this: function a() {} function b() {} b.prototype = object.create(a.prototype); function c() {} c.prototype = object.create(b.prototype); var inst = new c(); i can inst instanceof c == true, inst instanceof b == true, instanceof c == true. but how "iterate" constructor functions starting instance of c() it'd return function c(), function b(), function a() use instantiate instance. you can iterate prototypes doing for (var o=inst; o!=null; o=object.getprototypeof(o)) console.log(o); // {} // c.prototype // b.prototype // a.prototype // object.prototype however, iterate prototype chain. there no such thing "constructor chain". if want access constructors, need set .constructor property on prototypes appropriately when inheriting: function a() {} function b() {} b.prototype = object.create(a.prototype); b.prototype.constructor = b; function c() {} c.prototype = object.create(b.prototype); c.prototype.constructor = c...

(so, if variable x "needs" variable y calculated, there edge (y,x) ). now, since no-cyclic dependency, directed acyclic graph , can topol...
