The HTMLAreaElement.hash property returns a USVString containing a '#' followed by the fragment identifier of the URL.

The fragment is not percent-decoded. If the URL does not have a fragment identifier, this property contains an empty string, "".


// Getter
string = area.hash;
// Setter
area.hash = string;


Given this HTML
<map name="infographic">
  <area id="mdn-circle" shape="circle" coords="130,136,60" 
  href="" alt="MDN" />

<img usemap="#infographic" src="/media/examples/mdn-info.png" alt="MDN infographic" />
you can get the hash of the area link like this:
const area = document.getElementById("mdn-circle");
area.hash; // returns '#ExampleSection'
