Examples
Logging the value of elementTiming
In this example, adding the elementtiming attribute to the <img> element sets the image to be observed.
<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.
const el = document.getElementById("myImage");
console.log(el.elementTiming); // "big-image"
