How to efficiently iterate over nested arrays in JavaScript?
问题
我正在进行一个JavaScript项目，在这个项目中，我需要迭代一个嵌套的数组结构！每个嵌套的数组可以包含多层子数组，我需要对每个级别的元素执行一些操作？
目前，我正在使用嵌套的for循环来迭代数组，但我觉得这种方法不太高效，可能可以改进...我听说过像map、reduce和forEach这样的高阶函数，但我不太确定如何有效地在这种嵌套数组情景中使用它们。
有人可以指导我如何以最高效和简洁的方式在JavaScript中迭代嵌套数组吗？是否有特定的高阶函数或函数组合适用于这个任务？任何代码示例或建议将不胜感激！谢谢！
是的，我尝试过一些教程。
英文:
I'm working on a JavaScript project where I need to iterate over a nested array structure!? Each nested array can contain multiple levels of sub-arrays, and I need to perform some operations on the elements at each level?
Currently, I'm using nested for loops to iterate over the arrays, but I feel like this approach is not very efficient and could be improved... I've heard about higher-order functions like map, reduce, and forEach, but I'm not sure how to utilize them effectively for this nested array scenario.
Could someone please guide me on the most efficient and concise way to iterate over nested arrays in JavaScript? Is there a specific higher-order function or a combination of functions that would be suitable for this task? Any code examples or suggestions would be greatly appreciated! Thank you!?
yes, I have tried some tutorials

只展平它（array.flat(depthLevel)），然后循环遍历该结果。
将您的代码发布出来，下次回答会更容易。
英文:
Just flatten it (array.flat(depthLevel)) and loop over that result.
Post your code it'll be easier to answer next time.
