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 🙏

data-theory

v2.0.0

Published

A collection of data theory and structures in JavaScript.

Readme

Data Theory

This is a repository dedicated to data structures and data theory for JavaScript and in the future maybe C++ as Native Node Addons.

If you are looking for the original repository for this, you can find it in the original branch.

Benchmarks

If you would like to see some benchmarks on these data structures then click here...;

Theories & Structures

As theories and structures are built, I'll list them under this heading.

You won't see a todo list or a target list this time around. I'll take suggestions as issues on the repository, but I'm going to focus on building common structures and items one at a time. One thing I have learned as a developer is never get ahead of yourself, you can get paralyzed with planning and expectations.

  • LinkedStack: based on a linked list (slower)
  • UArrayStack: based on JS unbounded array (fast)
  • BArrayStack: based on JS bounded array (fastest)
  • LinkedQueue: based on a linked list (fast)
  • UArrayQueue: based on JS array unbound (very slow) Sadly this is the one most professionals teach and it is so wrong
  • BFixArrayQueue: based on JS array bounded but with fixed front at 0 index (slowest) only shown for educational purposes
  • BFltArrayQueue: based on JS array bounded but with floating front index (fastest)

Use in your projects

npm install data-theory
yarn add data-theory

Usage

const { queues } = require('data-theory');

let queue = new queues.LinkedQueue();

queue.enqueue('item');
queue.dequeue();

What is the original branch?

I moved the old repo to the original branch, this old repo was a different appraoch on how to do the data theory applications. I am redoing the entire repo and showing the new types and systems and making it importable.
