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 🙏

An implementation of Sets in JavaScript

Readme

Set.js

I created this because I noticed that there were no actual set object implementations in JavaScript and also to learn a bit more about creating node modules.

Usage

Create an array of items and then pass it to Set.
var Set = require('./set')
var set = new Set([0,1,1])
And then when we get it
set.get() // [0,1]

API

There are various Set functions available

Static functions

Set#unique given an array, return an array with all duplicates removed.

Instance functions

Set#contains return whether a given property is available.
Set#empty return whether the set in empty.
Set#size return the size of the Set.
Set#get return the set as an Array.

Set#add add an item to the Set.
Set#remove remove an item from the set.
Set#clear remove all items from the set.

Set#union return a new set that is the union of the set with another one.
Set#intersect return a new set that is the intersection of the set with another one.
Set#difference return a new set that is the difference of the set with another one.

Set#find return an array with all items that match the predicate.
