Wait for any promise to be fulfilled
npm install p-any> Wait for any promise to be fulfilled
Useful when you need the fastest promise.
You probably want this instead of Promise.race(). Reason.
With Node.js 15, there's now a built-in Promise#any method. The benefit of this package is that it has cancellation functionality.
``
$ npm install p-any
Checks 3 websites and logs the fastest.
`js
import pAny from 'p-any';
import got from 'got';
const first = await pAny([
got.head('https://github.com').then(() => 'github'),
got.head('https://google.com').then(() => 'google'),
got.head('https://twitter.com').then(() => 'twitter'),
]);
console.log(first);
//=> 'google'
`
