Have you ever wondered if there is an alternative for Cookies? 

You should, because there are limitation and downsides in using Cookies on your website that massively use this feature.

1. Cookies has limited size on most browsers
2. Cookies is transfer to server every page load
3. If you overload the size of the Cookies it will also eat up the space of session and might remove it

Introducing jStorage, a jQuery way of saving your data to the local client and I quote

jStorage is a cross-browser key-value store database to store data locally in the browser – jStorage supports all major browsers, both in desktop (yes – even Internet Explorer 6) and in mobile.

Yes it even support IE 6!

So how to use it in an easy way?

1. Include the following references to your project

   1. <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.8.0/jquery.min.js"></script>
      <script src="https://raw.github.com/andris9/jStorage/master/jstorage.js"></script>

2. Use $.jStorage.set(key, value) to save a value 
3. Use $.jStorage.get(key, “default value”) to get a value

And thats it you are now using jStorage.
