Patterns for Asynchronous Operations with async

I remember the good old days when running asynchronous operations required you to use callbacks in an ever-deepening pit of “callback hell”. Those days aren’t completely gone, but it’s simple enough to wrap functions that use callbacks to make them use promises instead.

The Complete Guide to New Promise Methods: Promise.allSettled() and Promise.any()

Since its introduction in ECMAScript 2015, the Promise object has provided two methods for tracking the state of asynchronous tasks: Promise.all() and Promise.race(). Although these methods have opened new possibilities in JavaScript, there are still use cases that aren’t covered. To fill this gap, two additional methods are proposed to be added to the specification: Promise.allSettled() and Promise.any().
