I can\'t find much information about Yii\'s AssetManager for the management of JS and CSS files. My question here is what is the point of using the AssetManager? I\'m not
I'm sure someone can answer this better than myself, but basically it's so that your source JS and CSS files can remain in your Protected folder.
This is a little more secure for one thing, but the main benefit to me is that you can compress and minify and otherwise process your assets with the asset publishing system, and it makes it easier to host your JS and CSS on a CDN since it's separate from your codebase.
Also, here's an official response from qiang (the guy who wrote Yii) about this.
