A useful but often overrated JavaScript function is the browser detect. Sometimes you want to give specific instructions or load a new page in case the viewer uses, for instance, Safari.

I advise you to use WhichBrowser. It’s up-to-date, and contains a treasure trove of mobile information.
If you use my old script I advise you to switch to WhichBrowser.
