在Node.js中处理嵌套的forEach

const asyncForEach = async (array, callback) => {
  for (let index = 0; index < array.length; index++) {
    await callback(array[index], index, array);
  }
};

const nestedForEach = async (nestedArray, callback) => {
  await asyncForEach(nestedArray, async (array) => {
    await asyncForEach(array, callback);
  });
};

// 使用示例
const nestedArray = [[1, 2, 3], [4, 5, 6], [7, 8, 9]];

nestedForEach(nestedArray, async (item) => {
  console.log(item);
  // 这里可以进行具体的处理逻辑
});
