Snippet that achieves Python's sleep

main.js

async function main() {
  console.log(`Start: ${performance.now()}`);
  await sleep(2000);
  console.log(`End: ${performance.now()}`);
}

sleep.js

function sleep(timeInMs) {
  return new Promise((resolve, reject) => {
      setTimeout(() => {
          resolve("Time up!");
      }, timeInMs);
  });
}
