Phoenix with LiveView is an antidote to the pernicious Web we weave. Massive concurrency, hydration, and that ever elusive stateful single page app experience, are all handled at the framework level instead of in the application. You write the app and it Just Works. If React or the JavaScript du jour isn’t already your horse in the race, Elixir is well worth a weekend test drive.

It even have a jupyter competitor in LiveBook[1].
