RTCStatsReport: values() method

The values() method of the RTCStatsReport interface returns a new iterator object that can be used to iterate through the values for each element in the RTCStatsReport object, in insertion order.

The values are statistics dictionary objects.

The method is otherwise the same as Map.prototype.values().



Return value


This example shows how to iterate through a RTCStatsReport using the iterator returned by values().

Given a variable myPeerConnection, which is an instance of RTCPeerConnection, the code calls getStats() with await to wait for the statistics report. It then uses a for...of loop, with the iterator returned by values(), to iterate through the dictionary objects in the report. The properties of statistics objects with the type of outbound-rtp are logged to the console (other objects are discarded).

const stats = await myPeerConnection.getStats();

for (const stat of stats.values()) {
  if (stat.type != "outbound-rtp") continue;
  Object.keys(stat).forEach((statName) => {
    console.log(`${statName}: ${report[statName]}`);
