Due to the growing diffusion of tools to compress and optimize JavaScript files (such Google Closure), I feel the need of an introduction of a standard way to identify and differentiate them (compiled files) from other uncompressed files. Basically, I would adopt a different file extension like CJS (which stands for compiled/compressed JavaScript). In this way it would be easy to browse a directory of hundreds of js files and identify those which are ready to be used in our project because already compressed and optimized.
What do you think about?
