Yahoo! open source Mojito - a JavaScript framework developed by Yahoo! for Web developers.

Mojito is a FREE 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.
