Lawnchair: Intro to Javascript library for persistent browser storage

I was reading http://dailyjs.com and discovered this  javascript library, Lawnchair: Simple JSON Storage, that is very lightweight (it is a lawnchair as opposed to a couch; 3.4k minified; 1.5 gzip’d) and uses a cascading set of techniques or adapters to store objects in memory that persists in the browser even after page refreshes.  Lawnchair is optimized for mobile and HTML5 browses, but defaults to in memory storage for older browsers.

This post is an Intro because I just discovered it. Once I use it,  I will post an article about my findings and title it “Lawnchair: Hands On Summary…”.  Hope this distinction helps.
