• Event-driven, reactive evaluation
• An event-stream abstraction for communicating with web services
• Interfaces to external web services

Flapjax is easy to learn: it is just a JavaScript framework. Furthermore, because Flapjax is built entirely atop JavaScript, it runs on traditional Web browsers without the need for plug-ins or other downloads. It integrates seamlessly with existing JavaScript code and other frameworks. [Source = http://www.flapjax-lang.org/]

Shriram Krishnamurthi is one of the authors of Flapjax and was in town recently giving a series of lectures to fellow programming language researchers in MSR. Shriram is a professor of computer science at Brown University. Expert to Expert host and programming language designer Erik Meijer is also doing some interesting things with event driven reactivity (you'll learn all about this soon...) so the two language guys just had to chat and we had to film it. Tune in to see what happened in Erik's office over the course of an hour or so. A fair amount of time is spent discussing the reasoning behind and benefits of adding types to a language like JavaScript. It's an interesting idea, but what does it mean for web developers (who, potentially, adopted JavaScript for its wide open and highly dynamic characteristics in the first place).

As usual, there's no editing here. It's as though you just came along and watched the magic unfold. Much thanks to Shriram for taking the time to chat with us. Flapjax is impressive. Do give it a try, Niners.
