一、Map与Object对比 a. 具体用法不同,Map是map.set()、map.get()、map.has()、map.delete(),Object可以直接obj.xx进行设置,in判断是否存在(有bug,可以拿到原型上的)等,Map的key可以重名(后者覆盖前者),Object的Key不可重名 b. Map可以用任意类型值作为key,Object必须用string、symbol作为key ...

This relation works in both directions by allow the value to also act as a key to key, e.g. a pair (a,b) thus provides a coupling between 'a' and 'b' so that 'b' can be found when 'a' is used as a key and 'a' can be found when 'b' is used as a key. type BidiMap...

简介:Java集合源码分析系列到此就结束了,关于Set的知识会在这里进行简单的总结,除此之外,则是学习之后的一些感受。Set概述Set是一个包含不可重元素的集合,也就是所有的元素都是唯一的。文档说明如下:A collection that contains no duplicate elements. More formally, sets contain no pair of elements e1 and e2...
