Cannot read properties of null (reading 'reduce')

"Cannot read properties of null (reading 'reduce')"是一个JavaScript的错误信息，表示在尝试对null对象的属性进行reduce操作时出错。具体原因可能是在代码中使用了null值而不是一个有效的对象。这种错误通常发生在对未定义的变量或对象进行操作时。解决这个问题的方法是确保在使用对象之前，先对其进行有效性检查，以避免对null值进行操作。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
