Logging the value of elementTiming

In this example, adding the elementtiming attribute to the <img> element sets the image to be observed.

html
<img
  src="image.jpg"
  alt="a nice image"
  elementtiming="big-image"
  id="myImage" />

You can get the string value of the elementtiming HTML attribute by calling el.elementTiming.

js
const el = document.getElementById("myImage");
console.log(el.elementTiming); // "big-image"

For a more complete example on how to use the Element Timing API, see PerformanceElementTiming.
