I Avoid Async/Await

Re:I Avoid Async/Await by bin_bash on Saturday April 16, 2022 @09:00AM (#31051960)

here's a real world example I use all the time:

    const wait = (ms = 500) => new Promise(resolve => setTimeout(resolve, ms));

then:

    async function () {
      await wait(1000);
    }

Perhaps it's hard to grok but it sure is a handy one-liner.

Of course in newer versions of node we can now do:

    import {
      setTimeout,
    } from 'timers/promises';

    await setTimeout(100);

There's no merit of what should be a project wide function being a single line instead of 3 to avoid "hard to grok" syntax.

Wait till you see the rest of javascript...

Your comment is snarky and categorically dismissive. Care to explain why you have taken such an aggressive stance against JS?

this works in older versions of node too:

const wait = require(‘util’).promisify(setTimeout)
