Node.js:我很难将回调函数的结果存储到字典变量中

const dictionary = {};

function asyncFunction() {
  return new Promise((resolve, reject) => {
    // 异步操作
    setTimeout(() => {
      const result = '回调函数的结果';
      resolve(result); // 将结果存储到字典变量中
    }, 1000);
  });
}

asyncFunction().then(result => {
  dictionary['key'] = result;
  console.log(dictionary);
}).catch(error => {
  console.error(error);
});

const dictionary = {};

function asyncFunction() {
  return new Promise((resolve, reject) => {
    // 异步操作
    setTimeout(() => {
      const result = '回调函数的结果';
      resolve(result); // 将结果存储到字典变量中
    }, 1000);
  });
}

async function main() {
  const result = await asyncFunction();
  dictionary['key'] = result;
  console.log(dictionary);
}

main().catch(error => {
  console.error(error);
});

const dictionary = {};

function asyncFunction(callback) {
  // 异步操作
  setTimeout(() => {
    const result = '回调函数的结果';
    callback(result); // 将结果存储到字典变量中
  }, 1000);
}

asyncFunction(result => {
  dictionary['key'] = result;
  console.log(dictionary);
});
