NavigatorUAData: toJSON() method

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The toJSON() method of the NavigatorUAData interface is a serializer that returns a JSON representation of the low entropy properties of the NavigatorUAData object.

Note: The terms high entropy and low entropy refer to the amount of information these values reveal about the browser. The low entropy values returned by this method are those which do not reveal information able to identify a user. High entropy values can only be returned by the NavigatorUAData.getHighEntropyValues() method.

Syntax

Parameters

None.

Return value

A JSON object.
