Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

expansion-type.js介绍

本包拓展了JavaScript的基础数据结构,已实现的数据结构如下

1.栈(Stack)

2.队列(Queue)

3.双端队列(Deque)

4.链表(LinkedListNode)

后续将逐步拓展更多的数据结构

简介

本包的源码实现均采用抽象接口(AbstractInterface)-->抽象类(AbstractClass)-->实现类(ImplementationClass)架构,源码请查看src目录下文件

各种数据结构的方法(未完善,持续更新中)


栈(Stack)结构的方法

push(element)

将一个元素压入栈顶。

  • 参数

    • element:要添加到栈顶的元素。
  • 示例

    stack.push(1);

pop()

移除并返回栈顶的元素。如果栈为空,返回 undefined

  • 返回

    • 栈顶元素或 undefined
  • 示例

    console.log(stack.pop()); // 输出: 3

peek()

返回栈顶的元素,但不移除它。如果栈为空,返回 undefined

  • 返回

    • 栈顶元素或 undefined
  • 示例

    console.log(stack.peek()); // 输出: 2

isEmpty()

检查栈是否为空。

  • 返回

    • true 如果栈为空,否则 false
  • 示例

    console.log(stack.isEmpty()); // 输出: false

size()

返回栈的元素个数。

  • 返回

    • 栈中元素的数量。
  • 示例

    console.log(stack.size()); // 输出: 2

clear()

清空栈。

  • 示例

    stack.clear();
