Kirish

1. TypeScript nima? Nima uchun kerak, JavaScript dan farqi
2. O'rnatish — tsc, Node.js, birinchi TypeScript fayl
3. Type annotation — qachon va qayerda yoziladi
4. tsconfig.json asoslari — strict va muhim sozlamalar

Asosiy Turlar

1. string, number, boolean — asosiy turlar
2. null, undefined, void — farqlari va ishlatilishi
3. any, unknown, never — qachon qaysi, xavflari
4. Array — T[] va Array<T>, readonly array
5. Tuple — aniq uzunlik, labeled tuple, optional element
6. Object tur — inline tipizatsiya, nested object
7. Type alias — yaratish, ishlatish, kengaytirish
8. Union turlar — | operatori, narrowing bilan ishlash
9. Intersection turlar — & operatori, mixin pattern
10. Literal turlar — 'qizil' | 42 | true, as const
11. Enum — numeric, string enum, const enum, qachon ishlatiladi

Interface

1. Interface — asoslar, sintaksis, ob'ekt shakli
2. Optional (?), readonly, Index signature
3. Interface extends — meros olish, bir nechta
4. Function interface — chaqiriladigan tur, construct signature
5. Interface vs Type alias — qachon qaysi, farqlari
6. Declaration merging — interface avtomatik birlashtirish

Funksiyalar

1. Funksiya parametr va qaytish turlari
2. Optional, default va rest parametrlar TypeScript da
3. Function overload — bir nom, turli imzo
4. Callback va higher-order funksiyalar tiplari
5. this parametri — kontekst turi, noImplicitThis

Type Narrowing

1. typeof guard — primitive turlarni tekshirish
2. instanceof guard — class instanсini tekshirish
3. in operator guard — xususiyat mavjudligini tekshirish
4. Discriminated union — tag field pattern
5. Type predicate (is) va exhaustiveness checking (never)

Generics

1. Generics nima uchun kerak? — muammo va yechim
2. Generic funksiyalar — T parametri, bir nechta parametr
3. Generic interface va type alias
4. Generic class — tur parametrli sinflar
5. Constraint (extends) va default type parametr
6. keyof, typeof operatorlari va lookup types (T[K])

OOP

1. Class — TypeScript da asoslar, oddiy JavaScript dan farqi
2. Access modifiers — public, private, protected
3. readonly xususiyatlar va parameter properties
4. Getter va Setter — TypeScript da
5. Static members va static initialization blocks
6. Abstract class — mavhum sinflar va metodlar
7. Interface implementation — implements, bir nechta interface

Ilg'or Turlar

1. Mapped types — { [K in keyof T]: ... }
2. Conditional types — T extends U ? X : Y
3. infer kalit so'zi — conditional type ichida tur chiqarish
4. Template literal types — `${string}Id`, Uppercase, Lowercase
5. Recursive types — o'ziga murojaat qiladigan turlar
6. Utility Types — Partial, Required, Readonly, Record
7. Utility Types — Pick, Omit, Extract, Exclude, NonNullable
8. Utility Types — ReturnType, Parameters, InstanceType, Awaited

Dekoratorlar

1. Dekorator nima? — experimentalDecorators, metadata reflection
2. Class dekorator — sinfni o'zgartirish va kengaytirish
3. Method dekorator — metodlarni wrapping qilish
4. Property dekorator — xususiyatlarni boshqarish
5. Parameter dekorator — parametrlarni belgilash

Modullar, Sozlash va Amaliy

1. Declaration files — .d.ts yaratish, @types, module augmentation
2. tsconfig.json to'liq — target, lib, paths, project references
3. TypeScript bilan React — props, hooks, events, children tiplari
4. TypeScript bilan Node.js va Express — tiplar, middleware, generic
