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 🙏

  • Chunk(array, [size=1])

将数组(array)拆分成多个 size 长度的区块,并将这些区块组成一个新数组。 如果array 无法被分割成全部等长的区块,那么最后剩余的元素将组成一个区块。

参数
  1. array (Array): 需要处理的数组
  2. [size=1] (number): 每个数组区块的长度
返回

(Array): 返回一个包含拆分区块的新数组(注:相当于一个二维数组)。

例子
_.chunk(['a', 'b', 'c', 'd'], 2);
// => [['a', 'b'], ['c', 'd']]

_.chunk(['a', 'b', 'c', 'd'], 3);
// => [['a', 'b', 'c'], ['d']]
  • Difference(array, [values])

创建一个具有唯一array值的数组,每个值不包含在其他给定的数组中。(注:即创建一个新数组,这个数组中的值,为第一个数字(array 参数)排除了给定数组中的值。)该方法使用SameValueZero做相等比较。结果值的顺序是由第一个数组中的顺序确定。

参数
  1. array (Array): 要检查的数组。
  2. [values] (...Array): 排除的值。
返回

(Array): 返回一个过滤值后的新数组。

例子
_.difference([3, 2, 1], [4, 2]);
// => [3, 1]
