    dat.GUI

    dat.GUI

    dat.gui is a lightweight controller library for JavaScript

    A lightweight graphical user interface for changing variables in JavaScript. The easiest way to use dat.GUI in your code is by using the built source at build/dat.gui.min.js. These built JavaScript files bundle all the necessary dependencies to run dat.GUI. If you're using a server with a Content Security Policy in place that blocks 'unsafe-inline', you will have problems when dat.gui.js tries to inject style information. To get around this, load 'build/dat.gui.css' as an external style sheet. With the npm run build script you can build development and production version of scripts. And with the npm run dev script you can build development version of script and watch for changes.

    jQuery Google Maps Store Locator Plugin

    jQuery Google Maps Store Locator Plugin

    A store locator plugin using Google Maps API version 3

    This jQuery plugin takes advantage of Google Maps API version 3 to create an easy to implement store locator. No back-end programming is required, you just need to feed it KML, XML, or JSON data with all the location information. How you create the data file is up to you. I originally created this for a company that didn’t have many locations, so I just used a static XML file. You will need to geocode your locations beforehand or use a geocoding API service if you want to try to do it on the fly. The reason for this is that all free geocoding APIs have strict limits that would easily be exceeded. In the end, you're much better off storing the coordinates versus having to look them up for each location on each request.

    v8n

    v8n

    JavaScript fluent validation library

    v8n aims to be the most fluent and simple validation library for use in any context. The API is beautifully readable and allows for easy creation of complex validations in any part of your app. Even though there are many useful default validation methods, it's a breeze to add your own fluent rules to v8n and use them anywhere in your app. The name v8n is actually derived from the structure of the word "validation". If you look closely you will find that between the v and the n, there are precisely 8 letters (a l i d a t i o). So we get from the sort of boring word validation to the very nice-looking acronym v8n.

    ARC-AGI

    ARC-AGI

    The Abstraction and Reasoning Corpus

    ARC-AGI is a benchmark dataset and experimental framework designed to evaluate and advance artificial general intelligence by testing systems on abstract reasoning tasks that require human-like problem-solving abilities. It consists of a curated set of tasks where models must infer patterns from input-output examples and apply those rules to new unseen cases, without relying on memorization or prior training data. The dataset is structured as grid-based puzzles, where each task requires understanding transformations such as symmetry, counting, or spatial manipulation. Unlike traditional machine learning benchmarks, ARC emphasizes generalization and reasoning over statistical pattern recognition, making it particularly challenging for current AI systems. The repository also includes a browser-based interface that allows humans to attempt solving the tasks manually, providing a baseline for comparison.

    JavaScript Style Guide

    The Airbnb JavaScript Style Guide is a widely adopted, opinionated, open-source set of coding conventions and best practices for writing readable, maintainable JavaScript (and React/JSX) code, published under the MIT license and assuming usage of modern tooling such as Babel and ESLint. Whichever testing framework you use, you should be writing tests. Strive to write many small pure functions, and minimize where mutations occur. Be cautious about stubs and mocks - they can make your tests more brittle.

    Bluebird

    Bluebird

    Full featured promise library with unmatched performance

    Bluebird is a fully featured promise library with focus on innovative features and performance. Promises in Node.js 10 are significantly faster than before. Bluebird still includes a lot of features like cancellation, iteration methods and warnings that native promises don't. If you are using Bluebird for performance rather than for those - please consider giving native promises a shot and running the benchmarks yourself. When using script tags the global variables Promise and P (alias for Promise) become available. Bluebird runs on a wide variety of browsers including older versions. Synchronous inspection allows you to retrieve the fulfillment value of an already fulfilled promise or the rejection reason of an already rejected promise synchronously. The default approach of bluebird is to immediately log the stack trace when there is an unhandled rejection.

    Emoji-Log

    Emoji-Log

    An Emoji Git commit log messages spec standard

    After building hundreds of open source software I've ended up inventing a git commit log standard called EMOJI-LOG that helps me understand a project's history with a less cognitive load just by looking at the git log. I like emoji. I like ’em a lot. Programming, code, geeks/nerds, open-source, all of that is inherently dull and sometimes boring. Emoji (which is, in fact, the plural of emoji) helps me add colors and emotions to the mix. Nothing wrong if you want to attach feelings to this 2D flat text-based world of code. I found out that instead of memorizing hundreds of emoji it's better to keep the categories small and general.
