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 read-only property
RTCPeerConnection.iceGatheringState returns an enum of type
RTCIceGatheringState that describes the ICE gathering state for the connection.
var state = peerConnection.iceGatheringState;
The possible values are those of an enum of type
"new": the object was just created, and no networking has occurred yet.
"gathering": the ICE engine is in the process of gathering candidates for this
"complete": the ICE engine has completed gathering. Events such as adding a new interface or a new TURN server will cause the state to go back to gathering.
var pc = new RTCPeerConnection(); var state = pc.iceGatheringState;
