Getting TypeError: results.forEach is not a function

Hi Cory,
First of all I would like to thank you very much for your wonderful course.
Although it's not suite for my developing level, it is very fruitful and it push me up the developing scale, hopefully one day to become an expert like you.

Now I am having the same issue of "TypeError: result.forEach is not a function..",
and I do not understand what should I set result to ? and how to solve this issue.
Very appreciate your assistant.

Meanwhile I solved it using regular for loop, but i would like to understand why it's not working as it should.
Thanks
Yigal

没有指定文件、测试或入口点，issue 也没有提供显示 results 值的代码。首先定位调用 results.forEach 的课程示例，并检查那里返回的值；只有在记录或修正 TypeError 的原因和预期的集合值后，issue 才算完成。

由索引模型根据 Issue 内容生成。
