Nodejs :使用回调合并函数

function mergeCallbacks(callbacks, finalCallback) {
  let count = callbacks.length;
  let results = [];

  callbacks.forEach((callback, index) => {
    callback((error, result) => {
      if (error) {
        finalCallback(error);
        return;
      }

      results[index] = result;
      count--;

      if (count === 0) {
        finalCallback(null, results);
      }
    });
  });
}

// 假设有两个异步操作需要执行
function asyncOperation1(callback) {
  setTimeout(() => {
    callback(null, 'Result 1');
  }, 1000);
}

function asyncOperation2(callback) {
  setTimeout(() => {
    callback(null, 'Result 2');
  }, 2000);
}

// 合并回调函数并执行
mergeCallbacks([asyncOperation1, asyncOperation2], (error, results) => {
  if (error) {
    console.error('Error:', error);
    return;
  }

  console.log('Results:', results);
});
