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 -

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 -

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.

D3.Js
Mike Bostock
D3.js is a JavaScript library for manipulating documents based on data. D3 helps you bring data to life using HTML, SVG, and CSS. D3’s emphasis on web standards gives you the full capabilities of modern browsers without tying yourself to a proprietary framework, combining powerful visualization components and a data-driven approach to DOM manipulation. D3 allows you to bind arbitrary data to a Document Object Model (DOM), and then apply data-driven transformations to the document. For example, you can use D3 to generate an HTML table from an array of numbers. Or, use the same data to create an interactive SVG bar chart with smooth transitions and interaction. D3 is not a monolithic framework that seeks to provide every conceivable feature. Instead, D3 solves the crux of the problem: efficient manipulation of documents based on data. This avoids proprietary representation and affords extraordinary flexibility, exposing the full capabilities of web standards such as HTML, SVG, and CSS. -

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 -

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
