1How to get a JavaScript sleep function
2
3First, you must sacrifice JS to the gods of asynchronous programming.
4Then, go to grepper and ctrl c + v some code with no idea how to use it.
5Give up.
6Realise you didnt need it in the first place.
7Die inside a little.
8Realise you should have stayed with python.
9Learn Java out of frustration.

1function sleep(milliseconds) {
2  const date = Date.now();
3  let currentDate = null;
4  do {
5    currentDate = Date.now();
6  } while (currentDate - date < milliseconds);
7}
8
9console.log("Hello");
10sleep(2000);
11console.log("World!");

1async function init() {
2  console.log(1);
3  await sleep(1000);
4  console.log(2);
5}

7function sleep(ms) {
8  return new Promise((resolve) => {
9    setTimeout(resolve, ms);
10  });
11}
12
13// one liner
14let sleep = ms => new Promise(resolve => setTimeout(resolve, ms));

1function sleep(ms) {
2  return new Promise(resolve => setTimeout(resolve, ms));

6  console.log('Taking a break...');
7  await sleep(2000);
8  console.log('Two seconds later, showing sleep in a loop...');

10  // Sleep in loop
11  for (let i = 0; i < 5; i++) {
12    if (i === 3)
13      await sleep(2000);
14    console.log(i);

1//Javascipt is asyncronous so you can't pause/block code execution
2//You can delay doing something with setTimeout
3setTimeout(function(){
4 	alert("Sup!"); 
5}, 2000);//wait 2 seconds
