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 🙏

比较两个数组中的不同

Readme

arr-different

使用 Commonjs 的形式写的简单模块。

arr-different 用于比较两个简单数组中不同元素都是有哪些。

使用

这个模块作为开发时依赖进行使用。

$ npm install arr-different --save-dev

引入该模块之后,直接使用方法进行比较。

// 参数必须是简单元素组成的数组
arrDiff([1,2,3], [2,3,4]);

最终生成的结果 :

[
  { ele: 1, diff: { left: "×", right: "√" } },
  { ele: 4, diff: { left: "√", right: "×" } }
]

其中 left 代表第一个参数的数组,right 代表第二个参数的数组。

最佳的使用方式,在使用 arrDiff 比较之前,最好去除数组中的重复元素

特别说明

也可以使用下面的安装方式,在 package.json 中加入下面的代码 :

"arr-different": "https://github.com/negivup/arr-different.git"

然后再 npm install
