We have the luxury of platinum element platinum-sw-cache which enables to offline manage the data.

Basically, I am trying to create an element that displays most recently used list of items in my application and I think caching is the way to do it.

How can I use the element to save an array such that It can be used later.

I do not find any usable Demo/Tutorial on this.
