Trouble in Paradise
JavaScript was conceived to be a single-threaded language where asynchronous tasks are handled with events. When there are only a few potential events, event-based code is much simpler than multithreaded code. Itâs conceptually elegant, and it eliminates the need to wrap up data in mutexes and semaphores to make it thread-safe. But when a number of events are expected, with state that needs to be carried from one event to the next, that simplicity often gives way to a code structure so terrifying that itâs been dubbed the Pyramid of Doom.
