How to get a JavaScript sleep function

First, you must sacrifice JS to the gods of asynchronous programming.
Then, go to grepper and ctrl c + v some code with no idea how to use it.
Give up.
Realise you didnt need it in the first place.
Die inside a little.
Realise you should have stayed with python.
Learn Java out of frustration.

sleep js

const sleep = ms => new Promise(r => setTimeout(r, ms));
sleep(5000)

OR

> npm i sleepjs

const { sleep } = require('sleepjs')
await sleep(500)

sleep javascript

//Javascipt is asyncronous so you can't pause/block code execution
//You can delay doing something with setTimeout
setTimeout(function(){
 	alert("Sup!"); 
}, 2000);//wait 2 seconds

js sleep

function sleep(milliseconds) {
  var start = new Date().getTime();
  for (var i = 0; i < 1e7; i++) {
    if ((new Date().getTime() - start) > milliseconds){
      break;
    }
  }
}
console.log('First');
sleep(1000);
console.log('Second');

javascript sleep function

sleep = milliseconds => new Promise(resolve => setTimeout(resolve, milliseconds));

//        V  Must add this async keyword
sayHi = async () => {
  	// V Must include await
	await sleep(1000); // Sleep 1000 milliseconds (1 second)
  	console.log('Hi');
  	// Rest of code...
}
