Elm already was the gold standard when it comes to helpful error messages and it's amazing to see that they're still working to make it even better. I hope other languages follow suit.
I use shairport-sync on my iMac to stream Overcast from the iPhone. There is a huge latency and the connection drops out every once in a while. This should have been a built in feature.
I'm actually writing Elm at work and we have two separate Elm apps in production.
YMMV but Elm with elm-graphql has been the most productive and confident I've ever been writing frontend code.
