Performance Testing JavaScript

Testing performance is surprisingly straightforward.

Start a timer
Run your tasks
Stop the timer and note how much time has elapsed

The performance.now() method
The console.time() and console.timeEnd() methods

<comp
  role="alert|log|status|progressbar|marquee|timer|region"
  aria-live="POLITENESS_SETTING = [off]|polite|assertive"
  aria-controls="IDLIST"
  aria-atomic="BOOLEAN = true|false"
  aria-relevant="LIST_OF_CHANGES"
  aria-labelledby="IDLIST"
  aria-describedby="IDLIST"
 aria-label="LABEL"
