You are developing a Windows Store app by using JavaScript. The app persists a list of restaurants in the app’s settings. The restaurant list is identified by a key of city.
The app must allow users to remove their restaurant lists from the app’s settings. The following function call removes the city setting:
deleteListSetting("city")
