nice! this might replace the explainer i usually handout for this concept https://www.youtube.com/watch?v=8aGhZQkoFbQ but Vivix seems

Philip Roberts' JSConf talk is one of the best technical explainers I've ever heard, it was a direct inspiration for the async module specifically. The main gap Vivix fills is async/await, that talk predates modern async patterns by about a decade. Curious whether the guided modules or freeform editor would be more useful.

Does it work with coding agents?

Not currently, Vivix is focused on helping developers and learners understand JavaScript execution at the instruction level: call stack, heap, async/await and more. Visualizing coding-agent output would be interesting though

woah so cool! do you plan to add support for other languages like python or go? this can be very helpful in learning new languages or algorithms

Thanks! Not yet, the hard part isn't reading the code, it's simulating how it runs. That logic is built specifically around JavaScript such as closures, async/await, the event loop, so another language means a new interpreter, not just a new parser. Python would be the most natural next step though
