在使用C++的时候我们经常会使用到各种容器,这些容器其实就是一种数据结构.在java中其实也是如此.但是由于javascript只给我们提供了一种内置的数据结构数组,准备来说是对象.没有我们常见的那些数据结构,但是在实际的工作中我们却不能离开这些常见的数据结构.所以我们只能去自己构造了. 虽然javascript中的数组的操作,比C++/java等操作数组方便的多,但是毕竟数组是一种对象,在对数据进行处理的时候效率还是很低的.所以有时候我们要自己构造想要的数据结构了. 定义(define): 链…
集合(set)是一组无序的,但彼此之间又有一定相关性的数据集.每个成员在数组中只能出现一次. 在使用集合(set)之前最好先理解一下内容: 1.不包含任何成员的集合称为空集合. 2.如果两个集合的成员都相等,两个集合相等. 3.如果一个集合中的成员都在另一个集合中,则两个具有父子集的关系. 在集合中我们常用的操作就是:求集合的并集,交集,补集等. 下面我们基于数组该构建一个集合(Set)类. <html> <head> <title>Date Example</t…
Dictionary常被称为数据字典,是一种用来保存键值对的数据结构,比如我们日常的电话本,就是一个Dictionary.我们通过键(名字),就可以访问到对应的值(电话号码).在C++与java中我们都是使用map来构建这样一个Dictionary,只是名字不同而已.在javascript中对象就好像是一个Dictionary一样,因为对象就是一个属性名/属性值的集合. 为了更好的体现出Dictionary,我们可以基于Array与object来构建一个使用方便简单的Dictionary类: D…
JavaScript data types and data structures Programming languages all have built-in data structures, but these often differ from one language to another. This article attempts to list the built-in data structures available in JavaScript and what proper…
To demonstrate the difference between mutability and immutability, imagine taking a drink from a glass of water. If our glass is mutable, when we take a drink, we retain the same glass and change the amount of water in that glass. However, if our gla…
"I worked up a full implementation as well but I decided that it was too complicated to post in the blog. What I was really trying to get across was that immutable data structures were possible and not that hard; a full-on finger tree implementation…
