NodeJS使用回调等待foreach的结束

function asyncForEach(array, callback) {
  return new Promise((resolve, reject) => {
    array.forEach((item, index) => {
      callback(item, index, array);
      if (index === array.length - 1) {
        resolve();
      }
    });
  });
}

async function main() {
  const array = [1, 2, 3, 4, 5];
  await asyncForEach(array, async (item) => {
    // 执行异步操作
    await doSomethingAsync(item);
  });
  console.log('循环结束');
}

main();

async function main() {
  const array = [1, 2, 3, 4, 5];
  for (const item of array) {
    // 执行异步操作
    await doSomethingAsync(item);
  }
  console.log('循环结束');
}

main();
