Hey, it would be great if you could merge this code into the primary UA Parser project here: https://github.com/ua-parser to unify dev efforts. The ua-parser project started out at Google as part of the BrowserScope project and both projects were opensourced.

It now has support for several languages including JavaScript, but I believe your project has some features that it lacks, for example, detecting the kind of device.
