npm install p-do-whilst
Choose your preferred style:
`js

let count = 0;
await pDoWhilst(
() => count++,
() => count < 5
);
console.log(count);
//=> 5
`
Or:
`js
import pDoWhilst from 'p-do-whilst';
const count = await pDoWhilst(
currentCount => currentCount + 1,
currentCount => currentCount < 5,
0
);
console.log(count);
//=> 5
