  1. Working on the Reactive lesson for my @rfortherest Shiny course. This is a course for Shiny beginners. Trying to figure out exactly how much detail about reactive programming to include. Mostly focusing on code mechanics (what corresponds to what).

      @rfortherest I will have a short section talking about how reactives are updated based on changes in input, and how what needs to be updated downstream is determined.by the reactive graph. I think that's about as far as I'll go. Any thoughts would be welcome.

        Debating whether to include observeEvent() as well, which would need a discussion on returned values versus side-effects. The terminology is exact, but it's also kind of daunting for beginners. Want to balance motivating beginners to start playing with examples, not scare them.

          I think one of the big issues with teaching Shiny is showing what parts of the code connect to other parts of code. Trying to manage cognitive overload has been challenging.

            That said, learners usually really want to learn Shiny and are motivated, so there's a little wiggle room there.
