Ramda
A practical functional library for JavaScript programmers
Ramda is a practical functional library for JavaScript programmers. There are already several excellent libraries with a functional flavor. Typically, they are meant to be general-purpose toolkits, suitable for working in multiple paradigms. Ramda has a more focused goal. We wanted a library designed specifically for a functional programming style, one that makes it easy to create functional pipelines, one that never mutates user data. The primary distinguishing features of Ramda are: Ramda emphasizes a purer functional style. Immutability and side-effect free functions are at the heart of its design philosophy. This can help you get the job done with simple, elegant code. Ramda functions are automatically curried. This allows you to easily build up new functions from old ones simply by not supplying the final parameters. The parameters to Ramda functions are arranged to make it convenient for currying. The data to be operated on is generally supplied last. -

React Slick
React carousel component
This library is the port of jQuery slick library. React slick is a carousel component built with React. It is a react port of slick carousel. The easiest way to try out react-slick is using the Code Sandbox example. After you are done installing through yarn or npm, now you will have to include CSS in your project. But be aware slick-carousel has a peer-dependancy on jQuery which you, or your colleagues may not like to see in your console output, so you can always grab the CSS from there and convert it into any CSS in JS solution that you might be using. -

React-Bootstrap
Bootstrap components built with React
React-Bootstrap replaces the Bootstrap JavaScript. Each component has been built from scratch as a true React component, without unneeded dependencies like jQuery. As one of the oldest React libraries, React-Bootstrap has evolved and grown alongside React, making it an excellent choice as your UI foundation. Built with compatibility in mind, we embrace our bootstrap core and strive to be compatible with the world's largest UI ecosystem. By relying entirely on the Bootstrap stylesheet, React-Bootstrap just works with the thousands of Bootstrap themes you already love. The React component model gives us more control over form and function of each component. Each component is implemented with accessibility in mind. The result is a set of accessible-by-default components, over what is possible from plain Bootstrap. -

Saka Key
A keyboard interface to the web
Saka Key lets you control your browser with keyboard shortcuts. It is easy to use, highly configurable and will transform how you surf the web. Put away your mouse. When the web isn't accessible, it's because people who author content don't understand the benefit of making it accessible. Saka Key leverages accessibility information to make the browsing experience better for everyone. I hope this will encourage the creation of accessible content. Keyboard shortcuts are only the beginning of this journey. Screen reading and voice commands are on the roadmap. Map keyboard keys to browser tasks like scrolling, clicking links, switching, moving, closing, muting, and refreshing tabs, zooming, and navigating pages. Keyboard shortcuts are flexible, powerful, and easy to customize. Saka Key lets you easily switch between shortcut profiles (e.g. left hand, right hand, default, Vimium), and lets you import and export your settings. -

Turndown
An HTML to Markdown converter written in JavaScript
Convert HTML into Markdown with JavaScript. to-markdown has been renamed to Turndown. See the migration guide for details. For usage with RequireJS, UMD versions are located in lib/turndown.umd.js (for Node.js) and lib/turndown.browser.umd.js for browser usage. These files are generated when the npm package is published. To generate them manually, clone this repo and run npm run build. Turndown also accepts DOM nodes as input (either element nodes, document nodes, or document fragment nodes). Options can be passed in to the constructor on instantiation. The key parameter is a unique name for the rule for easy reference. By default, Turndown does not keep any elements. The filter parameter works like a rule filter. To keep elements that are normally handled by rules, add a rule with the desired behaviour. -

UglifyJS 3
JavaScript parser, mangler, compressor, beautifier toolkit
UglifyJS is a JavaScript compressor/minifier written in JavaScript. It also contains tools that allow one to automate working with JavaScript code. A parser which produces an abstract syntax tree (AST) from JavaScript code. A code generator which outputs JavaScript code from an AST, also providing the option to get a source map. A compressor (optimizer). it uses the transformer API to optimize an AST into a smaller one. A mangler, reduce names of local variables to (usually) single-letters. A scope analyzer, which is a tool that augments the AST with information about where variables are defined/referenced etc. A tree walker, a simple API allowing you to do something on every node in the AST. A tree transformer, another API intended to transform the tree. All the above utilities and APIs are defined in ~6500 lines of code (except for the effective generation of the source-map, which is handled by the source-map module). Compared to alternatives, UglifyJS is pretty small.
