TaskAttributionTiming

{{SeeCompatTable}}{{APIRef("Performance API")}}

The TaskAttributionTiming interface returns information about the work involved in a long task and its associate frame context. The frame context, also called the container, is the iframe, embed or object that is being implicated, on the whole, for a long task.

You usually work with TaskAttributionTiming objects when observing long tasks.

TaskAttributionTiming inherits from {{domxref("PerformanceEntry")}}.
