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
metered = connection.metered
On return, metered
is true
if the user is being charged per unit of network usage; otherwise it's false
.
