JavaScript JavaScript Foundations Variables Null and Undefined

why is it ===?

the code challenge answer is myNullVariable === myUndefinedVariable. Can someone please help me understand this?

From my understanding === is a strict compare i.e. comparing results and data type. in this case myNullVariable is set to null and when using strict compare is never equal to myUndefinedVariable. Anybody can help?

You are right about how they operate. I see this question come around the forums from time to time, and it's usually confusion over what the challenge is actually asking you to do. Here is a link to a recent discussion about this challenge: https://teamtreehouse.com/forum/isnt-going-to-be-more-likely-to-equal-a-true-value-than-bit-confused-on-this-test

Hope that helps
