Penguins, properties and prototypes - stuck on 'properly define the Emporer Constructor'


I'm on Penguins, properties and prototypes lesson in Javascript language.
The below code throws the error of:
'Make sure to properly define the Emporer constructor'
In reading the forum, it was suggested to refresh the browser, or try a new tab, both of which I've done. If there is an error in the code, I can't see it and it appears to be correct according to other forum posts. Anyone have any ideas what is wrong with the Emporer constructor?

function Penguin(name) { = name;
    this.numLegs = 2;

function Emporer(name) { = name;

Emporer.prototype = new Penguin();

var bird = new Emporer("buddy");


Is it really spelled that way? What's the link to the exercise?


Not sure what spelling you are referring to, here's the link to the exercise though:


It says to make sure you defined something, you used a different name.


What he is trying to say is:

You spelled "emperor" wrong. Spell it the way I just did, and that should fix the error.


Thanks, using 'Emperor' with a capital E fixed it.
