Browser Detection

To establish the actual name of the user's Web browser, we can use thenavigator.appName and navigator.userAgent properties.

navigator.appName = Netscape

navigator.userAgent = Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.79 Safari/537.1

Firefox (and some other browsers) may return the string Netscape as the value ofnavigator.appName for compatibility with Netscape Navigator. 

However, that navigator.userAgent may be spoofed, too – that is, clients may substitute virtually any string for their userAgent.

browserName = Chrome

majorVersion = 21

fullVersion = 21.0.1180.79
