altJS

altJS is a collection of languages and tools aimed at rebooting JavaScript and making it better. Everything you'll find on this page is designed to output code for use on the web or with JavaScript-enabled servers and devices. This site is a handy guide to what's new in the altJS universe, as well as a place to connect.
