How to use the @lskjs/utils/getKeyValJson function in @lskjs/utils

locales.forEach((locale) => {
    const dirname = path.join(destination, locale);
    try {
      mkdirp.sync(dirname);
    } catch (err) {
      console.error(err);
    }
    fs.writeFileSync(`${dirname}.json`, JSON.stringify(getKeyValJson(localesRows, locale), null, 2)); // eslint-disable-line max-len
    // fs.writeFileSync(`${dirname}/translation.json`, JSON.stringify(getKeyValJson(localesRows, locale), null, 2)); // eslint-disable-line max-len
    const namespaces = groupBy(localesRows, 'ns');
    forEach(namespaces, (rows, ns) => {
      if (!ns) return;
      fs.writeFileSync(`${dirname}/${ns}.json`, JSON.stringify(getKeyValJson(rows, locale), null, 2));
    });
  });
};

forEach(namespaces, (rows, ns) => {
      if (!ns) return;
      fs.writeFileSync(`${dirname}/${ns}.json`, JSON.stringify(getKeyValJson(rows, locale), null, 2));
    });
  });
