我最近参加了一些在线课程，试图了解编程的基础知识，逐渐尝试增加我学习的复杂性。但是我似乎无法控制循环的输出，我得到最后一个值或[对象，对象对象，对象对象，对象，对象]
任何帮助都会非常感激，我相信这很简单，但是我已经尝试过为每个人提供帮助而且到目前为止都没有运气。

我希望有人可以帮助控制循环的输出。

您没有显示任何代码，但我猜您的问题是JavaScript中的典型问题：
JavaScript closure inside loops – simple practical example
查看neurosnap的答案。
http://coffeescript.org/#loops 在CoffeeScript中，它甚至更简单：
@Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> headerMap = new HashMap<>();
headerMap.put("Content-Type", "application/json");
//...
//headerMap.put("other keys", "other values");
//...
return headerMap;
}
基本上，你需要在JavaScript中的for循环中使用lambda / IIFE来循环以避免你的问题。
