Making SetTimeout Async Friendly

I love using the Async/Await syntax in ES6+ javascript. It keeps things simple and clean. I try my damndest avoid callbacks where possible in my code (unless a library I'm using expects or uses them--like with Express.js.)

I just want to say, I am by no means the author of this snippet, nor the first person to think it. Still, this is one of my favorite helper functions and I thought, why not share it--might make someone else's life easier too.

export const asyncTimeout = (ms: number) => { return new Promise((resolve) => { setTimeout(resolve, ms); }); }; 

A simple function, that simply takes in the amount of milliseconds you wish to wait as a parameter. We then immediately return a new Promise, which is resolved when setTimeout completes.

In action, it may look like this.

async function doStuff() { // doing stuff up here... await asyncTimeout(1000); // After waiting a second, continues doing stuff. } 

If anyone else has any awesome async helper functions they use, please share them!
