Javascript Continuations

Continuation support may have some advantages to make programming easier.
Imagine simpy having the complete state encoded in the
request and then a call to the server simply continues a function in the
same state where it stopped before.
No need to worries about any back buttons :-)

We know this from cocoons flowscript, but what does exist in pure javascript?

Here you can find a nice intro Continuation-Passing Style by Marijn Haverbeke, the creator of CodeMirror.

An an older post by Steve Yen, the creator of Trimpath Junction, about 'poor man' continuations: continuations-in-mozilla

What do we have to integrate it in javascript?
Well I found Narrative Javascript From Neil Mix
and Kirs Zip forked it to make add co-routines and co-threading possible
Strands, you know the "yield" thing :-) and also see jwacs by James Wright.

In this new post by Steve Continuations For JavaScript, Reloaded he points to Haili Wiki by Kevembuangga and its usage of continuations in a script continuation.js, modififing the function code on the fly..hmmm
