Status: VERIFIED INVALID

(Firefox :: Untriaged, defect)

Description

[Perry Smith]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:30.0) Gecko/20100101 Firefox/30.0 (Beta/Release)
Build ID: 20140605174243

Steps to reproduce:

o = {
    apple: 0
};

function Obj() {
}

Obj.prototype = Object.create(o, {
    meth: function () { return 1 + 2; }
});

f = new Obj();

f.meth();

A jsFiddle of this is here: http://jsfiddle.net/pedz/C2zLQ/1/
Turn on Firebug, hit run, and you will see the error.


Actual results:

calling f.meth() results in detailed error: TypeError: f.meth is not a function


Expected results:

No error should be produced.

This doesn't work in Chrome, either, because the code you're using is incorrect, as best I can tell. The second argument to Object.create should work for https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/defineProperties , and defineProperties takes object values of the form:

{
  meth: {
    enumerable: true,
    configurable: true,
    writable: true,
    value: function() { console.log("hello"); }
  }
}

(in particular, see http://jsbin.com/roxab/1/edit for a valid example along the lines of your testcase)
