    All supported language codes for map display and service responses.

    They set the language of map labels, place names, addresses and other textual content.

    The array includes:

    • Region-specific language variants (e.g., en-US, en-GB, pt-BR, pt-PT)
    • Script-specific variants (e.g., zh-Hans for Simplified Chinese, zh-Hant for Traditional Chinese)
    • Special codes like ngt (Neutral Ground Truth) for language-neutral content
    • Latin script alternatives (e.g., ngt-Latn, ko-Latn-KR, ru-Latn-RU)
    • Cyrillic script variants (e.g., ru-Cyrl-RU)

    Use it to check whether a user-provided language code is supported, to generate language selection UI or to iterate over all language options.

    // Validate a language code
    const userLanguage = 'en-US';
    if (languages.includes(userLanguage)) {
      console.log('Language is supported');
    }

    // Create a language selector
    languages.forEach(lang => {
      console.log(`Available language: ${lang}`);
    });

    // Check total number of supported languages
    console.log(`Total languages: ${languages.length}`);
