如何从javascript关联数组中删除对象？ - How do I remove objects from a javascript associative array?

问题：

Suppose I have this code: 假设我有这个代码：

var myArray = new Object();
myArray["firstname"] = "Bob"; myArray["lastname"] = "Smith"; myArray["age"] = 25; 

Now if I wanted to remove "lastname"?....is there some equivalent of 现在，如果我想删除“姓氏”？....是否有一些相当于
myArray["lastname"].remove() ? myArray["lastname"].remove() ？

(I need the element gone because the number of elements is important and I want to keep things clean.) （我需要元素消失，因为元素的数量很重要，我想保持清洁。）
