"translatedContent": "<p>请你编写一个函数，检查给定的值是否是给定类或超类的实例。</p>\n\n<p>可以传递给函数的数据类型没有限制。例如，值或类可能是 <code>undefined</code> 。</p>\n\n<p> </p>\n\n<p><strong>示例 1：</strong></p>\n\n<pre>\n<b>输入：</b>func = () => checkIfInstance(new Date(), Date)\n<b>输出：</b>true\n<strong>解释：</strong>根据定义，Date 构造函数返回的对象是 Date 的一个实例。\n</pre>\n\n<p><strong>示例 2：</strong></p>\n\n<pre>\n<b>输入：</b>func = () => { class Animal {}; class Dog extends Animal {}; return checkIfInstance(new Dog(), Animal); }\n<b>输出：</b>true\n<strong>解释：</strong>\nclass Animal {};\nclass Dog extends Animal {};\ncheckIfInstanceOf(new Dog(), Animal); // true\n\nDog 是 Animal 的子类。因此，Dog 对象同时是 Dog 和 Animal 的实例。</pre>\n\n<p><strong>示例 3：</strong></p>\n\n<pre>\n<b>输入：</b>func = () => checkIfInstance(Date, Date)\n<b>输出：</b>false\n<strong>解释：</strong>日期的构造函数在逻辑上不能是其自身的实例。\n</pre>\n\n<p><strong>示例 4：</strong></p>\n\n<pre>\n<b>输入：</b>func = () => checkIfInstance(5, Number)\n<b>输出：</b>true\n<strong>解释：</strong>5 是一个 Number。注意，\"instanceof\" 关键字将返回 false。</pre>\n",
