YUI Library

jQuery is a cross-platform JavaScript library designed to simplify the client-side scripting of HTML.

Lots of people use React as the V in MVC. Since React makes no assumptions about the rest of your technology stack, it's easy to try it out on a small feature in an existing project.

AngularJS lets you write client-side web applications as if you had a smarter browser. It lets you use good old HTML (or HAML, Jade and friends!) as your template language and lets you extend HTML’s syntax to express your application’s components clearly and succinctly. It automatically synchronizes data from your UI (view) with your JavaScript objects (model) through 2-way data binding.

It is a library for building interactive web interfaces. It provides data-reactive components with a simple and flexible API.

Whether you're building highly interactive web applications or you just need to add a date picker to a form control, jQuery UI is the perfect choice.

Prototype is a JavaScript framework that aims to ease development of dynamic web applications. It offers a familiar class-style OO framework, extensive Ajax support, higher-order programming constructs, and easy DOM manipulation.

If you've ever built a JavaScript application, the chances are you've encountered – or at least heard of – frameworks like React, Angular, Vue and Ractive. Like Svelte, these tools all share a goal of making it easy to build slick interactive user interfaces. Rather than interpreting your application code at run time, your app is converted into ideal JavaScript at build time. That means you don't pay the performance cost of the framework's abstractions, or incur a penalty when your app first loads.

Preact is an attempt to recreate the core value proposition of React (or similar libraries like Mithril) using as little code as possible, with first-class support for ES2015. Currently the library is around 3kb (minified & gzipped).

It is a JavaScript library that helps you to create rich, responsive display and editor user interfaces with a clean underlying data model.

Instead of writing reducers, caching logic, timers, retry logic, complex async/await scripting (I could keep going...), you literally write a tiny fraction of the code you normally would. You will be surprised at how little code you're writing or how much code you're deleting when you use this tool.

Tiny size(4KB gzip). Reactive data-binding. Based on Shadow Dom. Shadow DOM merges with Virtual DOM, Omi uses both virtual DOM and real Shadow DOM to make view updates more accurate and faster.

It is a declarative JavaScript library for creating user interfaces. It does not use a Virtual DOM. Instead it opts to compile its templates down to real DOM nodes and wrap updates in fine grained reactions. This way when your state updates only the code that depends on it runs.

Yoga is a cross-platform layout engine which implements Flexbox. Yoga enables maximum collaboration within your team by implementing an API familiar to many designers and opening it up to developers across different platforms.

T3 is different than most JavaScript frameworks. It's meant to be a small piece of an overall architecture that allows you to build scalable client-side code. T3 is explicitly not an MVC framework. It's a framework that allows the creation of loosely-coupled components while letting you decide what other pieces you need for your web application. You can use T3 with other frameworks like Backbone or React, or you can use T3 by itself.

React-server is a framework designed to make universal (née isomorphic) React easier to write, providing standard answers for these questions and more.
