// Soal 2: Buat arrayBaru dengan bentuk sebagai berikut:
// arrayBaru = [
//   { id: 70111470, title: "Die Hard" },
//   { id: 654356453, title: "Bad Boys" },
//   { id: 65432445, title: "The Chamber" },
//   { id: 675465, title: "Fracture" },
// ];

// Hint: Gunakan metode .map()

const arrayBaru = newReleases.map(function (item, index) {
  const objekBaru = {
    id: item.id,
    title: item.title,
    bookmarkId: item.bookmark.map((book) => book.id)[0],
  };
  return objekBaru;
});

console.log("arrayBaru: ", arrayBaru);

// Bonus: Dengan Arrow function

const arrayBaru2 = newReleases.map((item, index) => ({
  id: item.id,
  title: item.title,
  bookmarkId: item.bookmark.map((book) => book.id)[0],
}));
