在Array#map内部处理异步/等待中的错误(拒绝)

const array = [1, 2, 3, 4, 5];

const asyncFunction = async (value) => {
  // 模拟异步操作
  return new Promise((resolve, reject) => {
    setTimeout(() => {
      if (value === 3) {
        reject(new Error("出现错误"));
      } else {
        resolve(value * 2);
      }
    }, 1000);
  });
};

const mapAsync = async (array, asyncFunction) => {
  const results = [];
  for (const value of array) {
    try {
      const result = await asyncFunction(value);
      results.push(result);
    } catch (error) {
      console.error(error);
      // 处理错误或拒绝情况
    }
  }
  return results;
};

mapAsync(array, asyncFunction)
  .then((results) => {
    console.log(results);
  })
  .catch((error) => {
    console.error(error);
  });
