Promise.allSettled() Pt.2 - it's partly settled!
This is a follow-up to my first post on the upcoming
Promise.allSettled() function, coming soon to a node application near you.
Earlier today I was greeted by a Pull Request on my first post from GitHub user
It turns out there is a handy way to add
Promise.allSettled() to your apps right now! 🎉. It's fiendishly simple to use, too.

First, add the dependency to your project
> yarn add core-js
Then, at your app's entry point (usually something like
app.js in the root of your project):
or, if you want to include just the
Promise.allSettled() polyfill, and nothing else, use:
That's it! 🍻
