Project error

You have a mistake here in the quiz. It should pass with the == and fail with the ===, you have it the opposite. Oops!

The code challenge is working correctly. Since null and undefined are different you wouldn't want a identical() to run if the values of 2 variables were actually different.

Null and undefined are different, == does type coercion where === checks for strict equality.

Perhaps I read the quiz wrong. It seem the conditional if statement was initially comparing with == and the goal is to get the function within the block to be called. It should NOT run with === but it should run with ==. This seems contrary to the question. Thanks for the reply.
