Is Undefined==Null a falsey argument?

The code challenge is wrong. It takes undefined==Null as a falsey argument.

The answer, that is using '===', is stating that undefined===null is true, which is not.

undefined == null, will always be false.

That is because in js, null is a value of nothing. But undefined is not even a value, which is different to saying a value of nothing. Hopefully that makes sense.
