This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage 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 specification changes.
The RTCDataChannelEvent() constructor creates a new RTCDataChannelEvent.
You will rarely if ever construct an RTCDataChannelEvent by hand; these events are normally created and sent by the WebRTC layer itself.
Syntax
var event = new RTCDataChannelEvent(type, rtcDataChannelEventInit);
