🚀 TS Utility Types — Kodni Soddalashtiruvchi Super Vositalar! 🚀

TypeScript utility types yordamida kodni toza, tartibli, va o‘qilishi oson qilish mumkin. Quyida eng foydali TypeScript utils lar bilan tanishing!

🔥 Eng kerakli TypeScript Utility Types:
🔹 Awaited – Promise qaytaradigan funksiyalar natijasini olish uchun

type Result=Awaited

🔹 Record – Object tuzish uchun kalit va qiymat turini belgilaydi

type UserRoles = Record;

🔹 Omit – Object’ning ma’lum maydonlarini olib tashlaydi.

type User = { id: number; name: string; age: number };

type UserWithoutAge = Omit

🔹Required – Hammasi majburiy bo‘lgan object hosil qiladi

type User = { id?: number; name?: string };

type RequiredUser = Required; // id va name majburiy bo‘ladi

🔹 Readonly – Objectdagi barcha maydonlarni o‘zgarmas qiladi

type User = { id: number; name: string };

const user: Readonly = { id: 1, name: "Ali" };
// user.id = 2; ❌ Error

🔹 Pick – Object’ning faqat kerakli maydonlarini tanlab olish

type User = { id: number; name: string; email: string };
type UserInfo = Pick

🔹 Exclude – Bir turdan boshqasini olib tashlash

type Roles = "admin" | "user" | "guest"

type NonGuestRoles = Exclude

🔹 Extract – Faqat belgilangan qiymatlarni olish

type Roles = "admin" | "user" | "guest"


type AdminOnly = Extract; // "admin"

🔹 NonNullable – null va undefined ni chiqarib tashlaydi

type Name = string | null | undefined;


type SafeName = NonNullable; // faqat string

🔹 Parameters – Funksiya parametrlarini olish

type Func = (x: number, y: string) => void;

type Args = Parameters; // [number, string]

🔹 ReturnType – Funksiya natijasini olish

type Func = () => string;


type Result = ReturnType; // string

🔹 ReadonlyArray – O‘zgarmas array yaratish

const nums: ReadonlyArray = [1, 2, 3];
// nums.push(4); ❌ Error
