what do you mean async/await "replaced callbacks"? Async/await "replaced" Promises, specifically then/catch chaining. Turns out Promises can be syntactically-sugared to imperative try/catch blocks.
I’ll be more pedantic than that! Await is more akin to yield, the fact that it’s specific to promise resolution is a specialization of the more general function body suspension used by generators, with an extra specialization for event loop scheduling. And async just means you’re returning a promise no matter how your function exits.
hah, good point. Just wanted to point out that callbacks and async/await are different things, and callbacks are still the preferred way to customize behavior.
