title: Using html5 localstorage can I find the index corresponding to a key value
body: <pre><code>window.localStorage.setItem("Georgia","Atlanta") 
  var x=window.localStorage.getItem("Georgia")
  </code></pre>
  
  <p>I have a list of 50 states and the largest city stored in localstorage.
  Using the code above I can easily retrieve that Atlanta is the largest city for "Georgia".
  Is there an easy way to do a reverse lookup and search for "Atlanta" and get "Georgia"?</p>
