 <p>Traditionally, and according to ECMAScript, all objects are loosely unequal to <code>undefined</code> and <code>null</code>. But most browsers permit a very narrow class of objects (specifically, the <code>document.all</code> object for any page), in some contexts, to act as if they <em>emulate</em> the value <code>undefined</code>. Loose equality is one such context: <code>null == A</code> and <code>undefined == A</code> evaluate to true if, and only if, A is an object that <em>emulates</em> <code>undefined</code>. In all other cases an object is never loosely equal to <code>undefined</code> or <code>null</code>.</p>
