If you want to write the history of Python async things in order, you'll need to put Twisted in many more of the places: it was callbacks only in the very beginning, then worked via generators, and once Python added async syntax used that. "Twisted (callbacks)" is a simplification that ignores the influence Twisted has had even on non-Python ecosystems; Deferreds have been imitated all over the place.
- westurner 3y agoBefore callbacks, there were function pointers and there was no Garbage Collection; And before function pointers, there were JMPs, trampolines, and labels in ASM. I don't share any reverence for the Twisted callback patterns that AJAX also implements. And, the article isn't about callbacks. Promises in JS have a separate success and error functions. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Using_promises https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guid...
