在Javascript promise中嵌套.then()和catch

// 创建一个Promise
const promise = new Promise((resolve, reject) => {
  setTimeout(() => {
    resolve('Success!');
  }, 1000);
});

// 使用.then()和.catch()
promise
  .then(value => {
    console.log(value); // 输出: Success!
    return 'Another success';
  })
  .then(anotherValue => {
    console.log(anotherValue); // 输出: Another success
  })
  .catch(error => {
    console.error('Error:', error);
  });

promise
  .then(value => {
    console.log(value);
    return 'Another success';
  })
  .then(anotherValue => {
    console.log(another => anotherValue);
  })
  .catch(error => {
    console.error('Error:', error);
  });

async function handlePromise() {
  try {
    const value = await promise;
    console.log(value);
    const anotherValue = 'Another success';
    console.log(anotherValue);
  } catch (error) {
    console.error('Error:', error);
  }
}

handlePromise();
