Tugasmu disini adalah memodifikasi file-file berikut:
scripts/filterCarByAvailability.jsscripts/sortCarByYearAscendingly.jsscripts/sortCarByYearDecendingly.js
Dimana masing-masing file tersebut terdapat sebuah fungsi. Penjelasan terkait fungsi-fungsi tersebut dapat dilihat pada bagian selanjutnya.
Disini kamu akan membuat sebuah fungsi yang berguna untuk menyaring daftar mobil, yang mana dari daftar mobil tersebut ketika sudah disaring, akan menyisakan daftar mobil yang mana dapat disewa.
Input dari fungsi ini kita panggil cars, dimana tipe datanya adalah array of object. Untuk type signature dari input tersebut dapat dilihat pada definisi tipe di bawah ini:
type Car = {
id: string;
plate: string;
transmission: string;
manufacture: string;
model: string;
available: boolean;
type: string;
year: number;
options: string[];
specs: string[];
};
type Cars = Array<Car>;Contoh input:

]Ketika data cars dimasukkan ke dalam fungsi filterCarByAvailability,
maka hasil dari fungsi tersebut harus berupa Array<Car>
juga yang mana tiap item-nya memiliki atribut available yang bernilai true.
