为什么对象中的所有值都在 lodash 映射函数中更新？
Why all the values in the object are being updated inside lodash map function?
我在这里尝试根据键更新对象，但是在执行映射函数后，无论我是否尝试过滤键，所有值都会更新。

这是执行 map 函数后我得到的最终响应...我不明白对象中的每个值是如何更新的。

好吧，代码看起来很混乱，但最终的结论是
当我们尝试传播或克隆多级对象时，永远不会创建克隆，但新变量指向现有对象。
因此我们需要通过编写自定义函数或使用 lodash cloneDeep 函数来深度克隆对象。
我在这里尝试根据键更新对象，但是在执行映射函数后，无论我是否尝试过滤键，所有值都会更新。

好吧，代码看起来很混乱，但最终的结论是 当我们尝试传播或克隆多级对象时，永远不会创建克隆，但新变量指向现有对象。
因此我们需要通过编写自定义函数或使用 lodash cloneDeep 函数来深度克隆对象。
