in a dirty way you can use while (true) with date diffing to stop the loop but the question is: why do you need synchronous waiting?

No I mean there was console.log('first') after that setTimeout(console.log('hi') , 0) Question is how to make settimeout console to display first followed by first console?

you would like to await it

await new Promise(resolve => {
  setTimeout(() => {
    console.log('hi');
    resolve();
  }, 0) 
});
console.log('first');

await new Promise(resolve => {
  setTimeout(() => {
    console.log('hi');
    resolve();
  }, 0) 
});
console.log('first');

or .then() the promise instead of awaiting it !mdn await

!mdn Promise.prototype.then By the way, your question indicates that you are new to event loop (or asynchrony at all) inside JS. So i'd recommend you to get familiar with it: https://www.youtube.com/watch?v=8aGhZQkoFbQ https://javascript.info/async

When we use await So the output is console.log('hi') console.log ('first') Thanks u @ScriptyChris

though remember that await may only be used inside async function or at the top level of module file (or in console)
