It would be cool if the javascript were re-written a bit to only use standard long existing javascript features so one didn't have to run a modern corporate browser to use the "wander" functionality. It did not work in my browser even with JS enabled.
I am aware that I have used a number of relatively modern features. For example, I suspect `for ... of` might be one, and perhaps `Element.append()` (instead of `Node.appendChild()`) could also be an issue. Unfortunately, I do not have old browsers to test this reliably, so any help in identifying the exact constructs or functions causing problems would be very appreciated.
