Connection.metered
This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for the proper prefixes to use in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the spec changes.
The Connection.metered read-only property is a Boolean flag indicating if the connection is metered (e.g. pay-per-use).
Syntax
JavaScript
Copy Code
metered = connection.metered
On return, metered is true if the user is being charged per unit of network usage; otherwise it's false.
