Web/API/PerformanceMeasure

PerformanceMeasure is an abstract interface for PerformanceEntry objects with an entryType of "measure". Entries of this type are created by calling performance.measure() to add a named DOMHighResTimeStamp (the measure) between two marks to the browser's performance timeline.

Properties

This interface has no properties but it extends the following PerformanceEntry properties by qualifying/constrainting the properties as follows:

PerformanceEntry.entryType: Returns "measure".
PerformanceEntry.name: Returns the name given to the measure when it was created via a call to performance.measure().
PerformanceEntry.startTime: Returns a timestamp given to the measure when performance.measure() was called.
PerformanceEntry.duration: Returns a DOMHighResTimeStamp that is the duration of the measure (typically, the measure's end mark timestamp minus its start mark timestamp).

Methods

This interface has no methods.
