RTCStatsReport: size property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2020.

The size read-only property of the RTCStatsReport interface returns the number of items in the current report.

Note that each item consists of a key-value pair, where the keys are unique id values for monitored statistics objects from which the statistics are derived, and the associated values are statistics dictionary objects.

This property is otherwise the same as Map.prototype.size.

Value

An integer indicating the number of items in this report. The value is zero if the report is empty.
