JavaScript library/framework for Titanium Mobile

I've just took my first steps in mobile development with Titanium Mobile. Coming from PHP and JavaScript programming for the web, I'm really missing two things:

1. A JavaScript library
2. A MVC or similar "framework" to effectively separate logic and design

1. I've been googl开发者_如何学编程ing around and cannot seem to find a good answer. I tried taking the parts from MooTools that I wanted, but that didn't really work because, and this is where almost all JS libraries fail, even the core parts require window/navigator/dom, etc. I guess this could be done manually, but that doesn't sound like a future-proof way to go.

Does someone know a good library that bundles some of the most-used functions or, even better, know how to get MooTools core to work in Titanium?

2. Something that simplifies writing nice, structured code for Titanium Mobile. I could do this manually and I've read this question, but I'm looking for something/someone that already found the best way to do this :) and maybe even wrote a bit of code which could be re-used.

Thanks for your suggestions.
