带有多个promises的异步javascript函数，用于返回一个最终结果

function asyncFunction1() {
  return new Promise((resolve, reject) => {
    // 异步操作
    setTimeout(() => {
      resolve('Result 1');
    }, 1000);
  });
}

function asyncFunction2() {
  return new Promise((resolve, reject) => {
    // 异步操作
    setTimeout(() => {
      resolve('Result 2');
    }, 2000);
  });
}

function asyncFunction3() {
  return new Promise((resolve, reject) => {
    // 异步操作
    setTimeout(() => {
      resolve('Result 3');
    }, 1500);
  });
}

function asyncFunction4() {
  return new Promise((resolve, reject) => {
    // 异步操作
    setTimeout(() => {
      resolve('Result 4');
    }, 500);
  });
}

function asyncFunction5() {
  return new Promise((resolve, reject) => {
    // 异步操作
    setTimeout(() => {
      resolve('Result 5');
    }, 800);
  });
}

function asyncFunctionWithPromises() {
  const promises = [
    asyncFunction1(),
    asyncFunction2(),
    asyncFunction3(),
    asyncFunction4(),
    asyncFunction5()
  ];

  return Promise.all(promises)
    .then(results => {
      // 处理所有结果
      return results;
    })
    .catch(error => {
      // 处理错误
      throw error;
    });
}

asyncFunctionWithPromises()
  .then(finalResult => {
    console.log(finalResult); // 输出包含所有结果的数组
  })
  .catch(error => {
    console.error(error); // 输出错误信息
  });
