HTML5: Local Storage oddities & tips
HIJACKING localStorage<p>in chrome you can hijack basic functions in localStorage and then when they are called later, they call the replaced function.<p><pre><code>  localStorage.getItem = function(val){ console.log( val ); }
  //function (val){ console.log( val ); }
  localStorage.getItem( "truck" );
  //truck
  //undefined
  localStorage.getItem2 = function(val){ console.log( val ); }
  //function (val){ console.log( val ); }
  localStorage.getItem2( "truck" );
  //TypeError: Property 'getItem2' of object #&#60;a Storage&#62; is not a function
</code></pre>
localStorage keys can be any unicode character.<p><pre><code>  for( var i = 0; i &#60; 32000; i ++ ){ 
     localStorage[ String.fromCharCode(i) + "_test" ] = 
     String.fromCharCode(i) + "_test";
  }
</code></pre>
localStorage does not have a prototype<p>but, Storage.prototype is the prototype for localStorage, so you can add methods there.<p>localStorage NAMESPACING<p>i am wondering how one should namespace content on the same page large data sets seem dangerous.<p>localStorage private keys
if a key starts with a character that is not property safe, it must be accessed via the array notation localStorage[key] rather than dot notation.  using one of these chars in front of all of your keys could prevent you from overwriting key functions.<p>what are other localStorage hacks that you guys have found?
