const filterStars = (stars, checkFn) => {
  const result = [];
  for (const star of stars) {
    if (checkFn(star)) {
      result.push(star);
    }
  }
  return result;
};
const skyList = ['Sirius', 'Vega', 'Altair'];
const matched = filterStars(skyList, (name) => name.startsWith('A'));
console.log(matched);
