simpan.js 
Window Browser Local Storage API
simpan.js is a window.localStorage API. The HTML5 spec permits localStorage to only accept a String as value of an Object property, Simpan makes it possible to store entire JavaScript Objects.
Storing and Objects arguments
Simpan allows you to automatically store JavaScript Objects and not just strings (default localStorage behaviour), allowing you to do the following:
var person = {
id: 1,
name: 'Kamu',
members: ['Aku', 'Kamu', 'Dia', 'Mereka']
}
simpan.set('person', person);set API
To set data into localStorage, you must use the set() API. There are two arguments, key for the Object's key, and value for the key value:
simpan.set(key, value);get API
Obtaining set data is easy with the get() API, simply reference a previously set key with key:
simpan.get(key);delete || remove API
Deleting set data is easy with the delete() API, again reference a previously set key with key:
simpan.delete(key);clear API
It's a good idea to empty the user's localStorage when possible to avoid overloading it, there are limits which differ per browser.
