Preact
Preact
Preact provides the thinnest possible Virtual DOM abstraction on top of the DOM. It builds on stable platform features, registers real event handlers and plays nicely with other libraries. Most UI frameworks are large enough to be the majority of an app's JavaScript size. Preact is different: it's small enough that your code is the largest part of your application. That means less JavaScript to download, parse and execute - leaving more time for your code, so you can build an experience you define without fighting to keep a framework under control. Preact is fast, and not just because of its size. It's one of the fastest Virtual DOM libraries out there, thanks to a simple and predictable diff implementation. We automatically batch updates and tune Preact to the extreme when it comes to performance. We work closely with browser engineers to get the maximum performance possible out of Preact.Starting Price: Free -

Backbone.js
Backbone.js
Backbone.js gives structure to web applications by providing models with key-value binding and custom events, collections with a rich API of enumerable functions, views with declarative event handling, and connects it all to your existing API over a RESTful JSON interface. When working on a web application that involves a lot of JavaScript, one of the first things you learn is to stop tying your data to the DOM. It's all too easy to create JavaScript applications that end up as tangled piles of jQuery selectors and callbacks, all trying frantically to keep data in sync between the HTML UI, your JavaScript logic, and the database on your server. For rich client-side applications, a more structured approach is often helpful. With Backbone, you represent your data as Models, which can be created, validated, destroyed, and saved to the server.Starting Price: Free -

RequireJS
RequireJS
RequireJS is a JavaScript file and module loader. It is optimized for in-browser use, but it can be used in other JavaScript environments, like Rhino and Node. Using a modular script loader like RequireJS will improve the speed and quality of your code. This setup assumes you keep all your JavaScript files in a "scripts" directory in your project. To take full advantage of the optimization tool, it is suggested that you keep all inline script out of the HTML, and only reference require.js with a requirejs call like so to load your script. All of them map to loading some/path/some/module.js. Ideally we could choose the CommonJS syntax, since it is likely to get more common over time, and we want to reuse code.Starting Price: Free -

Download Velocity, include it on your page and replace all instances of jQuery's animate with velocity. You will immediately see a performance boost across all browsers and devices, especially on mobile. Velocity works everywhere, back to IE8 and Android 2.3. Under the hood, it mimics jQuery's queue, and thus interoperates seamlessly with jQuery's animate, fade, and delay. Since Velocity's syntax is identical to animate, your code doesn't need to change. JavaScript and jQuery are falsely conflated. JavaScript animation, which Velocity uses, is fast; it's jQuery that's slow. Although Velocity works alongside jQuery, it uses its own animation stack that delivers its performance.Starting Price: Free -

Three.js
Three.js
Three.js is a JavaScript 3D library. The aim of the project is to create an easy-to-use, lightweight, cross-browser, general-purpose 3D library. The current builds only include a WebGL renderer but WebGPU (experimental), SVG and CSS3D renderers are also available in the examples. To actually be able to display anything with three.js, we need three things, scene, camera, and renderer, so that we can render the scene with the camera. In addition to the WebGLRenderer, Three.js comes with a few others, often used as fallbacks for users with older browsers or for those who don't have WebGL support for some reason. Create a loop that causes the renderer to draw the scene every time the screen is refreshed (on a typical screen this means 60 times per second). Anything you want to move or change while the app is running has to go through the animate loop. You can of course call other functions from there.Starting Price: Free -

Modernizr tells you what HTML, CSS, and JavaScript feature the user’s browser has to offer. It’s a collection of superfast tests, or “detects” as we like to call them, which run as your web page loads, then you can use the results to tailor the experience to the user. All web developers come up against differences between browsers and devices. That’s largely due to different feature sets, the latest versions of the popular browsers can do some awesome things which older browsers can’t, but we still have to support the older ones. Modernizr makes it easy to deliver tiered experiences and make use of the latest and greatest features in browsers that support them, without leaving less fortunate users high and dry. Modernizr is a small piece of JavaScript code that automatically detects the availability of next-generation web technologies in your user's browsers.

Multiple.js
Multiple.js
An experiment in sharing background across multiple elements using CSS. If you want to accomplish a "background sharing across multiple elements" effect in HTML/CSS without any coordinates processing by JavaScript, Multiple.js is the answer. Note that icons and text at lighter layers have gradient-color from darker layers, creating the illusion of an underlying violet layer. In addition to that, layers pass the background image (girl) with equal transparency so that layers can not be superimposed on each other. All these things can be implemented in CSS. Add a gap between elements to make sure that the background remains in the same position. Toggle background image/gradient to get idea how it looks. Miss random layers to make sure that elements are independent. Expands background to viewport's size and displays in every element appropriate chunk, exactly what is needed! Background can be successfully expanded to full viewport size.Starting Price: Free -

React
React
React makes it painless to create interactive UIs. Design simple views for each state in your application, and React will efficiently update and render just the right components when your data changes. Declarative views make your code more predictable and easier to debug. Build encapsulated components that manage their own state, then compose them to make complex UIs. Since component logic is written in JavaScript instead of templates, you can easily pass rich data through your app and keep state out of the DOM. We don’t make assumptions about the rest of your technology stack, so you can develop new features in React without rewriting existing code. React components implement a render() method that takes input data and returns what to display. This example uses an XML-like syntax called JSX. Input data that is passed into the component can be accessed by render() via this.props.Starting Price: Free -

Nim
Nim
Nim is a statically typed compiled systems programming language. It combines successful concepts from mature languages like Python, Ada and Modula. Nim generates native dependency-free executables, not dependent on a virtual machine, which are small and allow easy redistribution. Nim's memory management is deterministic and customizable with destructors and move semantics, inspired by C++ and Rust. It is well-suited for embedded, hard-realtime systems. Modern concepts like zero-overhead iterators and compile-time evaluation of user-defined functions, in combination with the preference of value-based datatypes allocated on the stack, lead to extremely performant code. Support for various backends: it compiles to C, C++ or JavaScript so that Nim can be used for all backend and frontend needs.Starting Price: Free -

CoffeeScript
CoffeeScript
Underneath that awkward Java-esque patina, JavaScript has always had a gorgeous heart. CoffeeScript is an attempt to expose the good parts of JavaScript in a simple way. The golden rule of CoffeeScript is: “It’s just JavaScript.” The code compiles one-to-one into the equivalent JS, and there is no interpretation at runtime. You can use any existing JavaScript library seamlessly from CoffeeScript (and vice-versa). The compiled output is readable, pretty printed, and tends to run as fast or faster than the equivalent handwritten JavaScript. Most modern JavaScript features that CoffeeScript supports can run natively in Node 7.6+, meaning that Node can run CoffeeScript’s output without any further processing required. This list may be incomplete, and excludes versions of Node that support newer features behind flags; please refer to node.green for full details. You can run the tests in your browser to see what your browser supports.Starting Price: Free -
