TypeScript-da generics-larda klass turlaridan foydalanish
Umumlashtirilgan tur sifatida
klaslardan ham foydalanish mumkin.
Faqat uning konstruktori yordamida
klass turini belgilash kerak. Shuning uchun
type:T parametri o'rniga biz
type: {new(): T;} ni ko'rsatishimiz
kerak. Keling, o'z navbatida
User klasidan yangi foydalanuvchi
yaratadigan funksiyani yasaymiz:
function getUser <T> (type: { new (): T; }): T {
return new type();
}
class User {
constructor() {
console.log('You create a new user!');
}
}
let user: User = getUser(User);
Bajarilgan kod natijasi:
'You create a new user!'
