Implementing a Stepping Debugger in JavaScript

  very cool..!

  AFAIK the OP is the head behing the debugger of firefox devtools. Will this work be useful for the debugger or somehow enhance it? Just curious as I do not see the 'practical' merits of this work. Don't get me wrong, learning stuff and hacking by itself is always interesting – I'd just like to know if there is something in for me as a user of the firefox JS debugger.

    Can you rewind today?

    Nah, there is nothing from this that will benefit the Firefox devtools. It is an interesting space for me to play with ideas that would be a lot harder with native JS engines, but that's all. We are working on a new debugger interface, so stay tuned about that :)

  Very cool! I'm wondering if it will work on Nashorn. I actually have a need to be able to debug JavaScript code running inside Nashorn without touching the JVM debugger.

    The compiler may not because it uses a few node APIs, but those could be easily ported. The compiled code should definitely run; it's vanilla ES5 JavaScript.

      Thanks! I'll give it a try.
