Storage is just a javascript object, so it's properties can be
accessed any multiple ways:
preferences.getItem(theNameOfTheKey);
preferences.theNameOfTheKey
preferences[preferences[0]]
This makes the object that implements the interface tremendously
powerful and flexible. However, I agree that WebStorage should make
this more clear; but that should probably go into a primer, not in the
spec.
Try it out in Firefox's address bar:
javascript: localStorage.setItem("test", "test123");
javascript: alert(localStorage[localStorage[0]])
javascript: alert(localStorage.test)
The above will alert you "test123"
