title: Javascript: Retrieve all keys from sessionStorage?
body: <p>Is it not posssible to retrieve all keys/objects that I stored in sessionStorage (or localStorage)?</p>
  
  <p>If I have done <code>sessionStorage.name = 'John'</code> and <code>sessionStorage.city = 'New York'</code>, isn't there a way to get a list that shows the keys <code>name</code> and <code>city</code>?</p>
