Provides: Models, Collections (of model instances), Views (with declarative event handling). REST API support is baked in.

*The* JavaScript library.
"jQuery is a fast and concise JavaScript Library that simplifies HTML document traversing, event handling, animating, and Ajax interactions for rapid web development. jQuery is designed to change the way that you write JavaScript."

Interesting approach to MVC: each $$() object has its own model-view-controller stack. Model holds underlying data, view contains DOM template, controller takes care o event handling.

A love child of Backbone.js and Knockout.js, taking the best features from each one.

"Web application framework for a frontend built using RequireJS, Backbone.js, Underscore.js, jQuery, Mustache.js"

Details here: http://www.hautelooktech.com/2012/05/24/vertebrae-front-end-framework-built-with-backbone-js-and-requirejs-using-amd/

Interesting approach: add framework hooks in DOM, invent new HTML elements etc. Works with other libraries/frameworks.

"Batman.js is a framework for building rich web applications with CoffeeScript or JavaScript. App code is concise and declarative, thanks to a powerful system of view bindings and observable properties. The API is designed with developer and designer happiness as its first priority."

Library that allows binding of DOM elements to model data via HTML data attributes, implements Model-View-View-Model architecture, supports templating.

Micro-framework written in CoffeeScript, provides Classes, Models, Views, Controllers, can also handle Routes. Seems to be largely inspired from Backbone.js.

Ember takes the good ideas from SproutCore 1.x (Data Binding, State Charts), adds Handlebars.js templating.

Work in progress on a small library of useful JS components: a finite state machine / statechart thing, and a pub-sub implementation with namespaced events.

A list of Backbone plugins.

"Datavisualization.ch Selected Tools is a collection of tools that we, the people behind Datavisualization.ch, work with on a daily basis and recommend warmly. This is not a list of everything out there, but instead a thoughtfully curated selection of our favourite tools that will make your life easier creating meaningful and beautiful data visualizations."

Nice implementation.

Classes, MVC, routing.

"So here we're collecting all the shims, fallbacks, and polyfills in order to implant html5 functionality in browsers that don't natively support them.

The general idea is that: we, as developers, should be able to develop with the HTML5 apis, and scripts can create the methods and objects that should exist. Developing in this future-proof way means as users upgrade, your code doesn't have to change but users will move to the better, native experience cleanly."

"Dataset is a JavaScript client-side data transformation and management library. Dataset makes managing client-side data easy by handling loading, parsing, sorting, querying & manipulating data from all sorts of sources."

"Machina.js is a JavaScript framework for highly customizable finite state machines (FSMs). Many of the ideas for machina have been very heavily borrowed from the Erlang/OTP FSM behaviors."

"The main focus of CamanJS is manipulating images using the HTML5 canvas and Javascript. It's a combination of a simple-to-use interface with advanced and efficient image/canvas editing techniques. It is also completely library independent and can be safely used next to jQuery, YUI, Scriptaculous, MooTools, etc."

"A lightweight (3.7k) javascript date library for parsing, manipulating, and formatting dates."

"TodoMVC - a project which offers the same Todo application implemented using MV* concepts in most of the popular JavaScript MV* frameworks of today. Solutions look and feel the same, have a common simple feature-set and make it easy for you to compare the syntax and structure of different frameworks so you can select the one you feel the most comfortable with."

Just realized Photoshop has JavaScript automation. Should check it out sometime.

Useful roundup of JavaScript templating engines.

"The Annotator is an open-source JavaScript library and tool that can be added to any webpage to make it annotatable."

"Meteor is a set of new technologies for building top-quality webapps in a fraction of the time, whether you're an expert developer or just getting started."

"Modernizr is an open-source JavaScript library that helps you build the next generation of HTML5 and CSS3-powered websites."

"Look up HTML5, CSS3, etc features, know if they are ready for use, and if so find out how you should use them – with polyfills, fallbacks or as they are."

This seems a well-rounded guide to authoring jQuery plugins.

"Typed Arrays can significantly increase the pixel manipulation performance of your HTML5 2D canvas Web apps. This is of particular importance to developers looking to use HTML5 for making browser-based games."

"Mojito is a sweet (and minty!) MVC application framework built on YUI 3 that enables agile development of Web applications. Mojito allows developers to write client and server components in the same language (JavaScript), using the same framework. Because Mojito applications are written in JavaScript, they can run on the client (in the browser) and on the server (with Node.js). In addition, Mojito has built-in support for internationalization, testing, and building documentation."

"Enyo is an open source object-oriented JavaScript framework emphasizing encapsulation and modularity. Enyo contains everything you need to create a fast, scalable mobile or web application."

ExtJS-style declarative UI.

"AmplifyJS is a set of components designed to solve common web application problems with a simplistic API. Amplify's goal is to simplify all forms of data handling by providing a unified API for various data sources. Amplify's store component handles persistent client-side storage, using standards like localStorage and sessionStorage, but falling back on non-standard implementations for older browsers. Amplify's request adds some additional features to jQuery's ajax method while abstracting away the underlying data source."

Minification alone is quite useless. gzip is key (even used without packers).

"TypeButter allows you to set optical kerning for any font on your website. If you’re longing for beautifully laid out text that today’s browsers just don’t provide, this is the plugin for you!"

"PhoneGap is an HTML5 app platform that allows you to author native applications with web technologies and get access to APIs and app stores. PhoneGap leverages web technologies developers already know best... HTML and JavaScript."

Some good ideas in there (particularly using getters/setters).

Sound synthesis in JavaScript. Exciting!

"task.js is an experimental library for ES6 that makes sequential, blocking I/O simple and beautiful, using the power of JavaScript’s new yield operator."

It gives you a well-defined development environment with flexible routing, easy controller mappings, and basic request filtering. It’s built on open source libraries such as Hogan.js for view rendering, Klass for its inheritance model, Valentine for functional development, and Express to give a bundle of other Node server related helpers."

"Node is an exciting new platform developed by Ryan Dahl, allowing JavaScript developers to create extremely high performance servers by leveraging Google's V8 JavaScript engine, and asynchronous I/O. In Mastering Node we will discover how to write high concurrency web servers, utilizing the CommonJS module system, node's core libraries, third party modules, high level web development and more."

"JsFiddle is a playground for web developers, a tool which may be used in many ways. One can use it as an online editor for snippets build from HTML, CSS and JavaScript. The code can then be shared with others, embedded on a blog, etc. Using this approach, JavaScript developers can very easily isolate bugs. We aim to support all actively developed frameworks - it helps with testing compatibility."

More jQuery sugar with vanilla JavaScript.

I made this totally post-rock song with it -> http://www.technitone.com/view/lw6udoo0nb3

"Events in Javascript are often seen as a bit of an enigma. This is odd given that Javascript is very much an event driven language, but it is typically down to their complex nature and difficulty to debug. To this end I've created Visual Event to help track events which are subscribed to DOM nodes."

"Fabric.js is a framework that makes it easy to work with HTML5 canvas element. It is an interactive object model on top of canvas element. It is also an SVG-to-canvas (and canvas-to-SVG) parser.

Using Fabric.js, you can create and populate objects on canvas; objects like simple geometrical shapes — rectangles, circles, ellipses, polygons, or more complex shapes consisting of hundreds or thousands of simple paths. You can then scale, move, and rotate these objects with the mouse; modify their properties — color, transparency, z-index, etc. You can also manipulate these objects altogether — grouping them with a simple mouse selection.

You can add text on canvas and dynamically manipulate its size, alignment, fontfamily and other properties. You can apply filters to images, making them grayscale or removing background. You can serialize the entire canvas into a JSON string — saving it locally or on a server — then completely restore it at any time. You can also export canvas data back into SVG at any time."

Achieve jQuery sugar with plain old JavaScript.

The Dymo LabelWriter is a relatively inexpensive thermal printer with JavaScript API access that can be used to create something like BERG's Little Printer.
