Iterate Constructor Chain Up

Question

Assuming I have something like this:

function A() {}

function B() {}
B.prototype = Object.create(A.prototype);

function C() {}
C.prototype = Object.create(B.pr         


        

Answer 1

Go up the chain using the constructor property of the object's prototype.

For example, after your code:

 C.prototype.constructor === A

is true, as is

  inst.constructor.prototype.constructor === A

... and so forth.
