method Performance.mark
Usage in Deno
import { type Performance } from "node:perf_hooks";
Performance.mark(name: string,options?: MarkOptions,): PerformanceMark
Creates a new PerformanceMark entry in the Performance Timeline.
A PerformanceMark is a subclass of PerformanceEntry whose performanceEntry.entryType is always 'mark',
and whose performanceEntry.duration is always 0.
Performance marks are used to mark specific significant moments in the Performance Timeline.
The created PerformanceMark entry is put in the global Performance Timeline and can be queried with
performance.getEntries, performance.getEntriesByName, and performance.getEntriesByType. When the observation is
performed, the entries should be cleared from the global Performance Timeline manually with performance.clearMarks.
