<p>The <strong><code>HTMLHyperlinkElementUtils</code></strong> mixin defines utility methods and properties to work with {{domxref("HTMLAnchorElement")}} and {{domxref("HTMLAreaElement")}}. These utilities allow to deal with common features like URLs.</p>
<p>There are no objects of this type, but several objects {{domxref("HTMLAnchorElement")}} and {{domxref("HTMLAreaElement")}} implement it.</p>
