• PastryKit Interesting Features
• implements its own form of Object-Oriented Programming (obj.inherits and obj.synthetizes properties). When modules are declared, they're registered as a PK Class (i.e., PKClass(PKBarButtonItem) registers PKBarButtonItem as a PK Class.
• CSS3 wrapper functions (PKUtils.t() is a wrapper for translate3d, etc.)
• no single library namespace (suprisingly) - which means there are many many global variables. This however is somewhat acceptable, as all variables are prefixed with "PK" and are declared to be constant (const PKStartEvent, const PKEndEvent) and connot be overwritten.

There’s also some interesting takeaways not from PastryKit itself, but from the way the iPhone user guide is implemented. Most of the data on the page – including each menu icon (base64 encoded) – is located in a single 650kb JSON-encoded file called content.json. This means the initial loading of the page is quite slower than the user would normally expect, but once the initial payload has been delivered, it’s a relatively smooth browsing experience thereafter.

This data is stored locally in HTML5, allowing the user to continue reading even while offline.

Here's the slightly unminified version (using jsbeautifier.org) of the code
