原生javascript promise循环

function asyncOperation(i) {
  return new Promise((resolve, reject) => {
    // 异步操作，例如发送HTTP请求或读取文件等
    // 这里使用setTimeout模拟异步操作
    setTimeout(() => {
      console.log(`Async operation ${i} completed`);
      resolve(); // 异步操作完成后调用resolve
    }, 1000);
  });
}

function loopAsyncOperations(n) {
  let promises = [];
  
  for (let i = 0; i < n; i++) {
    promises.push(asyncOperation(i));
  }
  
  return Promise.all(promises);
}

loopAsyncOperations(5)
  .then(() => {
    console.log('All async operations completed');
    // 所有异步操作完成后的后续操作
  })
  .catch((error) => {
    console.error('An error occurred:', error);
    // 错误处理
  });
