Frozen

This challenge will need a bit of knowledge of one of the new features in Javascript 1.8.5, this feature is Object.freeze to get the correct result.

Correct!

False!

Note:

You can use anything of ECMASCRIPT 5 but not DOM or BOM, just Javascript
There is more than one answer but only the most simple will win.

Here you have the code to be fixed:

var dog = { sound: 'Bark!' }; Object.freeze(dog); /* Put your code here */ //This method should return 'Bark!' var result = dog.talk();

var dog = {
    sound: 'Bark!'
};

Object.freeze(dog);

Object.prototype.talk = function () {
    return this.sound;
};

//This method should return 'Bark!'
var result = dog.talk();

assert( result === 'Bark!');
