Add key-value pairs to javascript objects...(lesson needs revision)

I wanted to let the developers of this learning website to know that the lesson only explains how to call properties of an object and not how to add a property to the object with a value. I had to use google to search for the answer on how to add it. Although I am not against searching for the answer outside of this learning, i would expect the topic to have covered how to add key-value pairs and not only talk about how to call existing properties of an object.

You might want to review this challenge in the Basic JavaScript section. You have already learned how to do this.
