The packetsDiscarded property of the RTCInboundRtpStreamStats dictionary indicates the cumulative number of RTP packets that have been discarded by the jitter buffer due to late or early-arrival, and are hence not played out.

The value does not include packets that are discarded to due to packet duplication.
