What information can be determined from the navigator.userAgent property?
The navigator.userAgent property provides browser and system information: 1) It contains a string identifying the browser, its version, the operating system, device type, and rendering engine, 2) This string follows historical patterns that can be complex to parse reliably, 3) It can indicate if the browser is Chrome, Firefox, Safari, Edge, etc., 4) It includes platform information like Windows, macOS, iOS, Android, 5) It may contain device information for mobile browsers, 6) The format is not standardized and varies significantly between browsers, 7) It can be spoofed by browsers or browser extensions, making it increasingly unreliable for critical feature detection, 8) Modern web development best practices recommend feature detection over user-agent parsing whenever possible.
