NetworkInformation interface of the Network Information API provides information about the connection a device is using to communicate with the network and provides a means for scripts to be notified if the connection type changes.
NetworkInformation interface cannot be instantiated. It is instead accessed through the
connection property of the

This interface also inherits properties of its parent,
NetworkInformation.downlinkRead only Experimental
Returns the effective bandwidth estimate in megabits per second, rounded to the nearest multiple of 25 kilobits per seconds.
NetworkInformation.downlinkMaxRead only Experimental
Returns the maximum downlink speed, in megabits per second (Mbps), for the underlying connection technology.
NetworkInformation.effectiveTypeRead only Experimental
Returns the effective type of the connection meaning one of 'slow-2g', '2g', '3g', or '4g'. This value is determined using a combination of recently observed round-trip time and downlink values.
NetworkInformation.rttRead only Experimental
Returns the estimated effective round-trip time of the current connection, rounded to the nearest multiple of 25 milliseconds.
NetworkInformation.saveDataRead only Experimental
trueif the user has set a reduced data usage option on the user agent.
NetworkInformation.typeRead only Experimental
Returns the type of connection a device is using to communicate with the network. It will be one of the following values:
This interface also inherits methods of its parent,
