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 🙏

ArrayExtends

强化js原生数组

Install

npm i array-extends --save

Powerful

强化后数组将会拥有以下方法

asyncMap
asyncFind
asyncFilter
asyncSome
asyncEvery

clone
remove
removed
unique
max
sorted
topMap

Usage

const ArrayExtends = require('array-extends')

Example 1

// 执行主函数会赋予数组原型链 powerful 函数
// Array.prototype.powerfull
// 后续所有原生数组实例皆可访问该方法进行强化
// 注意:该方式会修改数组原型链,在数组原型链添加 powerfull 方法
ArrayExtends()

// 获得强化数组
const arr = [1, 2, 3].powerful()
// 克隆一个强化数组,注意使用slice克隆后的结果非强化数组
const tmp = arr.clone()

async function double(item) {
    return item * 2
}

await tmp.asyncMap(async(item) => {
    return await double(item)
})

Example 2
如果不想修改原生数组原型链,可以使用下面这种方法

// 一样可以获得强化数组,不修改原型链的情况下
const arr = ArrayExtends.powerful([1, 2, 3])
// 克隆一个强化数组
const tmp = arr.clone()

async function double(item) {
    return item * 2
}

await tmp.asyncMap(async(item) => {
    return await double(item)
})

Example 3 强化整个原生数组原型链的方法

ArrayExtends.ArrayExtends()
