Emotion is a library designed for writing css styles with JavaScript. It provides powerful and predictable style composition in addition to a great developer experience with features such as source maps, labels, and testing utilities. Both string and object styles are supported. There are two primary methods of using Emotion. The first is framework agnostic and the second is for use with React. Similar to the style prop, but also has support for auto vendor-prefixing, nested selectors, and media queries. ...

Underscore.js is a JavaScript utility-library created by Jeremy Ashkenas that provides a broad set of functions for working with arrays, objects, functions, and other data types — essentially a “utility belt” for functional programming in JS. Instead of extending built-in objects or modifying prototypes, Underscore provides its helpers in a single _ namespace, enabling cross-browser support and consistent behaviour across environments. It offers map/filter/reduce, deep-cloning, templating,...

This repository is a curated collection of small, focused React examples intended to illustrate core concepts through runnable code. Each demo isolates a single idea—such as component composition, state and props, lifecycle hooks, or event handling—so learners can see cause and effect without framework noise. The code favors clarity over abstraction, making it easy to copy, tweak, and compare different approaches to the same problem. Many examples are deliberately minimal, showing just enough HTML, CSS, and JavaScript to highlight the React pattern being taught. ...

...All components come with proper attributes and keyboard interactions out of the box. Quickly and easily reference values from your theme throughout your entire application, on any component. Components were built with composition in mind. You can leverage any component to create new things.

Introduction to Vue.js 3 Course houses the workshop materials for an “Introduction to Vue.js” course created by Sarah Drasner, originally delivered on Frontend Masters. The content covers essential Vue.js concepts such as directives, data rendering, methods, watchers, computed properties, components, slots, and the Composition API (for Vue 3), complemented with example code and exercises. Since the course was updated for Vue 3, the repo includes directories for both Vue 2 and Vue 3 resources, enabling learners to explore both versions depending on their work context. Also included are build setups (Vue CLI, Nuxt) and additional sections on animation and advanced topics like custom directives, making it a full learning path rather than just a quick tutorial. ...

Callbag Basics is an open-source JavaScript library that provides reusable utilities for reactive and iterable programming using the Callbag specification. It unifies push-based event streams and pull-based iterables through a simple communication protocol. Developers can create data sources from arrays, promises, browser events, and intervals. Common operators perform transformations such as mapping, filtering, scanning, merging, and flattening sequences. The same operators can work with...

...The author explicitly described the library as experimental and unsuitable for production. Development ended after Vue introduced an official hooks-inspired composition model, making the repository mainly useful as a historical design experiment.
