I’m not 100% sure, as I just completed my ES6 course but I believe you need to look where you’re strings are ending. Remember we can use a plus operator to concatenate parameters (I apologize if that is not the correct syntax) to strings.

This line raises a ReferenceError: _$Second is not defined error because hasOwnProperty accepts a string and is being passed an undefined variable. Try wrapping _$Second in quotes to pass the name as a string instead.

Beyond that, you are logging the promise itself. If you instead want to log the message that is resolved, you can change the last line to:

logMyBirthDate.then(console.log)

Same for the rejected message, substituting then for catch.
