id property

int? get id

The read-only RTCDataChannel property id returns an ID number (between 0 and 65,534) which uniquely identifies the RTCDataChannel. This ID is set at the time the data channel is created, either by the user agent (if RTCDataChannel.negotiated is false) or by the site or app script (if negotiated is true).

Each RTCPeerConnection can therefore have up to a theoretical maximum of 65,534 data channels on it, although the actual maximum may vary from browser to browser.
