WorkerNavigator: connection property

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

Note: This feature is only available in Web Workers.

The connection read-only property of the WorkerNavigator interface returns a NetworkInformation object containing information about the system's connection, such as the current bandwidth of the user's device or whether the connection is metered. This could be used to select high definition content or low definition content based on the user's connection.
