everybody always points to the 5 line basics, never to how complex async/await gets in a real system with timers, tuneouts, multiple errors types that need to be handled in different ways, heartbeats, side channel info, etc... It isn't better at that point.
Cool, you can write a 5 line echo server easier, but good luck with a high performance server handling important transactions.
(If there is documentation on how to do some of these or good example code, please point me to it, because my last attempt at getting send/rcv heartbeats efficiently didn't work.)
