It also has an \[[ErrorData]] slot, like all built-in exceptions.

Additionally, if an implementation gives native {{Error}} objects special powers or
nonstandard properties (such as a <code>stack</code> property),
it should also expose those on {{DOMException}} objects.
Since {{DOMException}} objects have an \[[ErrorData]] slot, the
<code>Error.prototype.stack</code> accessor and other {{Error}}-related behaviors
gated on \[[ErrorData]] apply to them. Additionally, if an implementation gives
native {{Error}} objects other special powers or nonstandard properties, it should
also expose those on {{DOMException}} objects.
