Thanks a lot for the good ideas. I hope my amendments make sense. Would love to hear feedback from you.

Suggested change

	it('when gets passed an object, it will copy the reference and fill the array with references to that object.', function(){
	it('when passing an object, it will copy the reference and fill the array with references to that object', function(){

just a picky change :)

Actually, I just copied the whole sentence from MDN 😅

When the fill method gets passed an object, it will copy the reference and fill the array with references to that object.

I'm not confident at all, but it feel like that it should be a passive voice.

I don't understand the test description and how it is supposed to make the user arrive at the solution.
What I understand from the test description would be the following code (passing test).

const obj = {};
const arr = Array(1).fill(obj);
assert.equal(arr[0], obj);

wouldn't it?

[jizusun]

Yes, you're right 😂

Hi sir, is it better now?
