It's important to note that Titanium will refuse to load JavaScript files from a remote URL. Loading remote JavaScript from a URL and providing it with the full capabilities of the Titanium API would be very dangerous.When your Window is loaded from a separate JavaScript file, the code will be executed in a separate JavaScript context (called a sub-context) than your app.js global context. It will also execute in its own separate thread",
