The [@@iterator]() method of the RTCStatsReport interface implements the iterable protocol and allows statistics reports to be consumed by most syntaxes expecting iterables, such as the spread syntax and for...of loops. It returns an iterator object that yields the key-value pairs of the report in insertion order.
The initial value of this property is the same function object as the initial value of the RTCStatsReport.entries() method.
The method is otherwise the same as Map.prototype[@@iterator]().
