当存在“ goog.object”时,对“ goog.structs”有什么需求?

[英]What is the need of 'goog.structs' when 'goog.object' is there?

What is it that goog.structs provides which goog.object does not? goog.structs提供了哪些goog.object没有提供什么? I went through the documentation but didn't find anything satisfying, except the top line of goog.structs saying: 我浏览了文档,但没有发现任何令人满意的内容,除了goog.structs的第一行说:

Generics method for collection-like classes and objects. 类似于集合的类和对象的泛型方法。

What is a collection-like class or object in javascript? 什么是javascript中类似集合的类或对象? As far as I know, about javascript every object satisfies being 'collection-like'. 据我所知,关于javascript,每个对象都满足“类似集合”的要求。

What am I missing here? 我在这里想念什么?

goog.structs is a namespace containing a wide variety of specific classes for specific things, like CircularBuffer , Trie , Queue , Set , and so on. goog.structs是一个名称空间,其中包含用于特定事物的各种特定类,例如CircularBufferTrieQueueSet等等。 goog.object is a fairly basic container. goog.object是一个相当基本的容器。
