如何从调用$ .getJSON的函数返回一个值？

function getJSON(url) {
  return new Promise(function(resolve, reject) {
    $.getJSON(url, function(data) {
      resolve(data);
    }).fail(function() {
      reject('Error: Unable to fetch data');
    });
  });
}

getJSON('https://api.example.com/data')
  .then(function(data) {
    console.log('Data:', data);
  })
  .catch(function(error) {
    console.error('Error:', error);
  });

async function getJSON(url) {
  try {
    const data = await $.getJSON(url);
    return data;
  } catch (error) {
    throw new Error('Error: Unable to fetch data');
  }
}

(async function() {
  try {
    const data = await getJSON('https://api.example.com/data');
    console.log('Data:', data);
  } catch (error) {
    console.error('Error:', error);
  }
})();
