The alt property of the HTMLAreaElement interface specifies the text of the hyperlink, defining the textual label for an image map's link. It reflects the <area> element's alt attribute.
The alt value must be text that, when presented with the alt text of the other <area> hyperlinks within the same <map>, along with the alt text of the <img> itself, provides the user with the same kind of choice as the hyperlink would when used without its text but with its shape applied to the image.
If the <area> is a link (contains an href property), the alt property value should be a non-empty string giving the label for the link that would be appropriate if the image were unavailable. The alt attribute for a link <area> can only be empty if there is another <area> element in the same <map> that points to the same resource and has a non-blank alt attribute.
A string.
Examplesconst areaElement = document.getElementById("imageArea");
console.log(areaElement.alt);
areaElement.alt = "A much better link description";
