+
+<p><code><strong><em>function</em>.arguments</strong></code> 属性代表传入函数的实参，它是一个类数组对象。</p>
+
+<h2 id="描述">描述</h2>
+
+<p><code><em>function</em>.arguments</code> 已经被废弃了, 现在推荐的做法是使用函数内部可用的 {{jsxref("Functions/arguments", "arguments")}} 对象来访问函数的实参。</p>
+
+<p>在函数递归调用的时候（在某一刻同一个函数运行了多次，也就是有多套实参），那么 <code>arguments</code> 属性的值是最近一次该函数调用时传入的实参，下面的示例有演示。</p>
+
+<p>如果函数不在执行期间，那么该函数的 <code>arguments</code> 属性的值是 <code>null</code>。</p>
