Stupid fallback for localStorage when browser doesn't support it

localStorageFallback.js

/**
 * Warning : only use this piece of code 
 * if storing things in the localStorage is 
 * NOT vital for your application to work
 **/
 
/* function noop 
 * simply does nothing
 **/
function noop() {}

/**
 * if window.localStorage is defined then `storage` 
 * will contain it. Else `storage` will simply be a 
 * stupid mock for localStorage and won't store anything
 */
var storage = window.localStorage || {
  length: 0,
  key: noop,
  setItem: noop,
  getItem: noop,
  removeItem: noop,
  clear: noop
};

/**
 * Then you can use `storage` like you would use `window.localStorage`
 * without worrying about browser compatibility
 * /

Hey Thomas, agree with you on that :(
btw, for avoiding to declare an empty function, you can use directly Function.prototype :)
