具有相同间隔的多个setTimeout()函数的执行顺序

async function runTimers() {
  await new Promise(resolve => setTimeout(resolve, 1000));
  console.log('Timer 1');
  await new Promise(resolve => setTimeout(resolve, 1000));
  console.log('Timer 2');
  await new Promise(resolve => setTimeout(resolve, 1000));
  console.log('Timer 3');
}

runTimers();
