Currently we use YUI Compressor in order to minimize our JS and CSS. It would be better to compress JS files using Google Closure Compiler. This will give us the following benefits:
1. Google Closure Compiler compresses data much better, which will improve the performance.
2. It supports Source Maps, which will allow us to debug the minimized files.
