method Performance.mark
Usage in Deno
```typescript import { type Performance } from "node:node__perf_hooks.d.ts"; ```
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`.
