The helper example was a sore attempt to plug the project I've been working on (tinkering with it is how I came up with the example). The library I plugged has much more to do with enabling a more flexible reactive programming model in js, but just so happens to plug into the stream API pretty handily. Still an interesting look IMO if you're into that kind of stuff
No worries, I know how it feels! (I said, plugging away my own project in a sibling comment, lol)
I do like the reactive approach (in fact, I’ve reinvented something similar over SSE). I feel a standards-based solution is just ever so slightly more robust/universal.
