How can I make the setTimeout function synchronous?

Question

My code gives output (with a delay between lines):

one
three
((2 seconds delay))
two

How can I make the code synchronous so that it shows output:

one
((2 seconds delay))
two
three

The code:

console.log('one'); 
setTimeout(() => {
    console.log('two');
}, 2000);
console.log('three');

You can use promises with setTimeout to achieve this! The trick is to resolve the promise when the setTimeout finishes — Nick Zuber, Nov 08 '19 at 14:51

function x() {
  var promise = new Promise(resolve => setTimeout(() => resolve("2"), 3000));
  return promise;
}
async function y() {
  console.log("1");
  var y = await x();
  console.log(y);
  console.log("3");
}
y();
