Lambda the Ultimate

Narrative Javascript is an extension to Javascript that adds an operator to convert asynchronous operations into synchronous ones. It has a compiler that compiles the extended Javascript into normal Javascript.

It provides on the client side what continuation based web frameworks do on the server side. Instead of manually splitting up your code into callbacks and handlers for events, setTimeout, XMLHttpRequest callbacks, etc you write your code in a sequential manner.

The code is CPS transformed and the continuations at the point of use of the new operator are used for the callbacks - allowing continuation of the function when done.

It looks pretty nifty.
