A new language and live environment made for the web.
The Amber language is deeply inspired by Smalltalk. It is designed to make client-side development faster and easier. Amber includes a live development environment with a class browser, workspace, unit test runner, transcript, object inspector and debugger.
Having a true live & incremental development environment where you can build your application interactively in the browser is unbeatable.
Smalltalk stands head and shoulders above most other languages for clarity, conciseness, and human-friendliness. As a language, it is immensely clean and mature, both syntactically and semantically. It is a pure OO language, with objects all the way down.
