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.
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
