My experience of JavaScript is nowhere near that good. While it does not have parallelism, the concurrency is as unrestricted as it is in go, forgetting awaits is a very common issue leading to wild tasks running unbounded and unchecked, and when you need any other synchronisation mechanism you have to write them yourself and they’re tricky indeed. $dayjob’s JS team keeps chasing concurrency issues, and breaking builds because of them.
