In reply to @isofruit "I mean sure, but": Sorry for slow reply, had to nap: our 1-week old has been draining our batteries so to speak. Then it got late and I decided to follow up the next day. > I regard frontend as fundamentally event driven Absolutely, me too. > Ixjs seems to be best described as "When the technical task is so big reactive just makes no sense" ... That latter scenario I encounter rarely, to say the least Interesting take, but definitely not my use cases for it or how I think about when to use pull versus push. Here are my thoughts, I put them in a gist since it got a little long: https://gist.github.com/michaelsbradleyjr/1346bfb362401bde3090f5995bee0d56 Concurrency and reactivity are problem spaces I enjoy exploring, but if you're not interested in additional discussion of push/pull at this time, no problem.
