performance property

Performance get performance

The performance property of the WorkerGlobalScope interface returns a Performance object, which can be used to gather performance information about code running in the worker's scope.

Performance entries are per context. If you create a mark on a worker thread, you will not see it in the main thread or any other workers.

Note that only the following performance interfaces are available in worker contexts:

• Performance
• PerformanceEntry
• PerformanceMark
• PerformanceMeasure
• PerformanceObserver
• PerformanceObserverEntryList
• PerformanceResourceTiming
• PerformanceServerTiming

Implementation

external Performance get performance;
