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!
