Life was hard before these sugars.
Just a couple of years ago I spent a few months with people stuck in the late 2000s, technologically speaking. Their JS was your typical jQuery spaghetti from that time period. Did not have any fun explaining the new stuff, not to mention Promises, to people who were somehow convinced they knew better than me.
Yeah I had an argument on here about callbacks vs. Promises. I’m pretty convinced the ones making the pro callbacks arguments have never actually used JavaScript in a professional capacity, especially in large codebases. I thought the callbacks vs Promises using `async/await` debate was settled.
I’ve never heard anyone argue for callbacks. But the async/await problem isn’t entirely dead since folks still argue generators should be doing they job. They’re similar flavors of cooperative multitasking I guess. But callbacks.. they’re really hard to test without abusing entirely different parts of js. Not that promises are much better.
Yes, but async await isn't really complete without good support for streaming ops and APIs that support them first class. That includes merging streams, canceling them, etc (kinda like Rx). It probably needs both push and pull streams as well. We're not there yet, so in the meantime we have to use events and event listeners, in addition to async/await. I think that's perfectly fine.
