<p><code><strong>WeakSet.prototype</strong></code> 속성(property)은 {{jsxref("WeakSet")}} 생성자에 대한 프로토타입을 나타냅니다.</p>

<div>{{js_property_attributes(0,0,0)}}</div>

<h2 id="설명">설명</h2>

<p>{{jsxref("WeakSet")}} 인스턴스는 {{jsxref("WeakSet.prototype")}}에서 상속합니다. 모든 <code>WeakSet</code> 인스턴스에 속성 또는 메서드를 추가하기 위해 생성자의 프로토타입 객체를 사용할 수 있습니다.</p>

<p><code>WeakSet.prototype</code>은 그 자체로 그냥 평범한 객체입니다:</p>

<pre class="brush: js">Object.prototype.toString.call(WeakSet.prototype); // "[object Object]"</pre>
