It doesn't look like you've written any code yet.

Please give it your best "good faith" attempt, and then post your code along with a link to the challenge if you need some help.

If you're totally stuck, here's a hint that may get you going:
The "syntactic sugar" the challenge is referring to is the "arrow" notation that can be used for computed properties. Review the Expression Bodied Members video, and be sure to pay special attention to the example starting at around time index 1:27.
