You are developing a Windows Store app by using JavaScript. The app persists a list of stocks in the app’s settings. The stock list is identified by a key of stockList.
The app must allow users to remove their stock lists from the app’s settings. The following function call removes the stockList setting:
deleteAppSetting("stockList")
You need to remove only stockList from the settings storage without disrupting other settings.
