NavigatorUAData interface of the
User-Agent Client Hints API returns information about the browser and operating system of a user.
An instance of this object is returned by calling
Navigator.userAgentData. Therefore, this interface has no constructor.
Note: The terms high entropy and low entropy refer to the amount of information these values reveal about the browser. The values returned as properties are deemed low entropy, and unlikely to identify a user. The values returned by
NavigatorUAData.getHighEntropyValues() could potentially reveal more information. These values are therefore retrieved via a
Promise, allowing time for the browser to request user permission, or make other checks.
