# Software Engineering — Intervyuga Tayyorgarlik (O'zbek tilida)

Dasturchilar uchun intervyuga tayyorgarlik bo'yicha to'liq bilimlar bazasi — **JavaScript va TypeScript** asosida. Har bir mavzu **kerakli tushunchalar + intervyu savollari + javoblar** ko'rinishida yozilgan, ishlaydigan kod misollari bilan.

> Maqsad: **Frontend**, **Backend** va **Database** bo'yicha asoslardan tortib system design darajasigacha tayyorlash.

> Tushuntirishlar o'zbek tilida; kod, kalit so'zlar va standart texnik atamalar (closure, event loop, JOIN va h.k.) ingliz tilida — chunki real intervyularda aynan inglizcha atamalar ishlatiladi.

## Bu repo nima? (About)

Bu — **o'zbek tilidagi ochiq (open source) dasturchilar bilimlar bazasi va intervyuga tayyorgarlik qo'llanmasi**. Maqsad — o'zbek yoshlariga sifatli, tizimli va bepul ta'lim resursini yetkazish, chunki bunday chuqur materiallar ko'pincha faqat ingliz tilida bo'ladi.

**Kimga mo'ljallangan:**
- Ishga kirishga tayyorlanayotgan junior/mid dasturchilar.
- O'z bilimini tizimlashtirmoqchi bo'lganlar.
- Frontend, Backend, Database, DevOps yoki System Design'ni chuqur o'rganmoqchi bo'lganlar.

**Nima bor:** 16 ta bo'lim — nazariya + intervyu savol-javoblari + yechimsiz masalalar (alohida yechimlar bilan) + amaliy loyiha g'oyalari + deployment qo'llanmalari + ~875 terminlik lug'at.

**Ochiq manba (open source):** bu repo hammaga bepul va ochiq. Uni o'qishingiz, ko'chirishingiz, tarqatishingiz va yaxshilashingiz mumkin — [MIT litsenziyasi](./LICENSE) asosida. Xato topsangiz yoki qo'shimcha qilmoqchi bo'lsangiz — [hissa qo'shing](#hissa-qoshish-contributing)!

## Bu repodan qanday foydalanish kerak

- Har bir bo'limning o'z papkasi va `README.md` mundarijasi bor.
- Fayllar o'rganish tartibida raqamlangan.
- Hujjat ichidagi belgilar:
  - **💡 Tushuncha** — bilishingiz shart bo'lgan asosiy g'oya.
  - **❓ Intervyu savoli** — intervyuda so'raladigan ko'rinishda.
  - **✅ Javob** — moslashtirib aytsa bo'ladigan namunaviy javob.
  - **⚠️ Ehtiyot bo'l** — keng tarqalgan xatolar va qo'shimcha savollar.
  - **🧪 Kod** — JS/TS misollari.
- Har bir mavzuning oxirida **## Masalalar** bo'limi bor — yechimlarsiz. Yechimlar alohida [`solutions/`](./solutions/) papkasida joylashgan, shu strukturani takrorlaydi.

## 📖 Lug'at (Terminlar)

Ingliz tilidagi texnik terminlarning o'zbekcha ma'nolari — to'g'ridan-to'g'ri tarjima emas, **tushunish uchun izoh** bilan. Har bir bo'limning o'z lug'ati bor (`<bo'lim>/LUGAT.md`), hammasi birlashtirilgan umumiy lug'at esa: **[LUGAT.md](./LUGAT.md)**.

## Tavsiya etilgan o'rganish tartibi

1. **Avval asoslar**: JS → TS → HTML → CSS.
2. **Yo'nalish tanlang**: Frontend (React) yoki Backend (Node) — yoki ikkalasi.
3. **Database parallel**: SQL asoslarini erta, advanced + design keyinroq.
4. **Networking parallel**: backend bilan birga TCP/DNS/proxy/latency.
5. **System design oxirida**: hammasini bog'laydi.
