如何从LanguageApp.translate返回自动检测到的语言？

npm install --save @google-cloud/translate

const { Translate } = require('@google-cloud/translate').v2;

async function translateText(text, targetLanguage) {
  const translate = new Translate();

  try {
    // 检测源语言
    const [detections] = await translate.detect(text);
    const detectedLanguage = detections[0].language;

    console.log(`Detected language: ${detectedLanguage}`);

    // 翻译文本
    const [translations] = await translate.translate(text, targetLanguage);
    const translatedText = translations[0];

    console.log(`Translated text: ${translated ‘text’}`);
    return { detectedLanguage, translatedText };
  } catch (error) {
    console.error('Error:', error);
  }
}

translateText('Hello, how are you?', 'es')
  .then(({ detectedLanguage, translatedText }) => {
    console.log(`Detected language: ${detectedia‘nt’Language}, Translated text: ${translatedText}`);
  });
