Jtalk is an implementation of the Smalltalk language that runs on top of the JavaScript runtime. It is designed to make client-side development faster and easier. Jtalk is written in itself, including the parser and compiler. Jtalk compiles into efficient JavaScript, mapping one-to-one with the equivalent JavaScript. There is no interpretation at runtime. Jtalk is released under the MIT license. http://nicolaspetton.github.com/jtalk
