PerformanceTiming: unloadEventEnd property

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

[!WARNING] This interface of this property is deprecated in the Navigation Timing Level 2 specification. Please use the {{domxref("PerformanceNavigationTiming")}}  interface instead.

The legacy PerformanceTiming.unloadEventEnd read-only property returns an unsigned long long representing the moment, in milliseconds since the UNIX epoch, the {{domxref("Window/unload_event", "unload")}}  event handler finishes. If there is no previous document, or if the previous document, or one of the needed redirects, is not of the same origin, the value returned is 0.

Value

An unsigned long long.
