Some Javascript developers, when presented with an API, think, “I know, I’ll make it async!” Now their users have a giant mess of a state machine implemented with callbacks and recursion, in a GC runtime that doesn’t eliminate tail calls, and two orders of magnitude worse performance. Normally, I wouldn’t care, because you get what you ask for when you write something in Javascript, but this time it happened to a project that I occasionally maintain for $work. And so I was sad.
