Check the Browser compatibility table carefully before using this in production.

This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

This property is obsolete. Use RTCDataChannel.ordered instead in any new code, and update existing code as soon as possible.


var reliable = aDataChannel.reliable;


true if the RTCDataChannel's connection is reliable; false if it isn't.
