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.


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

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


This interface has no methods.


See the example in Using the User Timing API.
