#Foydali #JS #null #undefined #Tutorial

🤔 "Null" va "undefined" o'rtasidagi farq nima?

JavaScript-dagi "null" qiymat yoki ob'ekt mavjud emasligining aniq belgisidir, "undefined" esa o'zgaruvchi yoki xususiyat e'lon qilingan, lekin ishga tushirilmaganligini bildiradi. "null" ishlab chiquvchi tomonidan qo'lda belgilanadi va "undefined" hali qiymat olmagan o'zgaruvchilarga avtomatik belgilash natijasidir. Mantiqiy kontekstda ikkala qiymat ham noto'g'ri deb hisoblanadi, ammo ulardan foydalanish kodning ma'nosiga qarab farqlanadi. "null" ko'proq ob'ektni kutayotgan o'zgaruvchilarni ishga tushirish uchun ishlatiladi.

1. JavaScript nima? Nega uni o‘rganish kerak?

ℹ️ JavaScript (JS) – bu veb-saytlar, dasturlar va hatto serverlarni yaratishda ishlatiladigan kuchli dasturlash tili.

🔴 JS Nimaga Kerak?

~~✅ Dinamik veb-sahifalar yaratish~~
~~✅ Tugmalar, animatsiyalar, modal oynalar qo‘shish~~
~~✅ Ma'lumotlarni qayta ishlash va API'lar bilan ishlash~~

🔴 Dastlabki "JS" kodingiz

Quyidagi kod ekranga "Salom, JavaScript!" deb chiqaradi:

console.log("Salom, JavaScript!");

Bu kodni browserning console oynasida yoki Node.js muhiti orqali ishlatishingiz mumkin!

❓Savol: "JavaScript" qaysi sohalarda ishlatiladi? Kommentda fikr qoldiring!

⏭ Keyingi postda "JavaScriptni qanday ishlatamiz?" yoritiladi.

2. JavaScriptni Qanday Ishlatamiz?

JavaScript kodini uch xil usulda ishlatish mumkin:

1️⃣ HTML ichida <script> orqali

Eng oddiy usul – HTML hujjatining ichida yozish:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>JS Boshlanishi</title>
</head>
<body>
    <h1>Salom, JavaScript!</h1>

    <script>
        alert("Bu JavaScript!");
    </script>
</body>
</html>

📌 Bu kod sahifa yuklanganda alert oynasini chiqaradi.

2️⃣ Alohida ".js" fayl orqali

Kodingizni alohida .js faylga yozib, HTML bilan bog‘lash yaxshiroq:

<script src="script.js"></script>

📌 Bunda barcha JavaScript kodi script.js faylida bo‘ladi.

3️⃣ Brauzer console orqali

Agar siz tezda kodni tekshirmoqchi bo‘lsangiz:
1️⃣ Chrome yoki Firefox’ni oching
2️⃣ F12 tugmasini bosing
3️⃣ Console oynasiga quyidagi kodni yozing

console.log("JavaScript ishladi!");

📌 Bu kod console’da "JavaScript ishladi!" deb chiqaradi.

3. HTML, CSS va JavaScript –
ularning farqi nima?

ℹ️ Agar veb-dasturlashni o‘rganmoqchi bo‘lsangiz, uchta asosiy texnologiyani bilishingiz kerak:

🟠 HTML – Tuzilma (Structure)

HTML (HyperText Markup Language) – bu veb-sahifaning asosiy skeleti. U matnlar, rasmlar, tugmalar va boshqa elementlarni joylashtirish uchun ishlatiladi.

Misol:

<h1>Bu sarlavha</h1>
<p>Bu oddiy matn.</p>

🟠 CSS – Dizayn (Style)

CSS (Cascading Style Sheets) – veb-sahifalarga go‘zallik beradi. Rang, shrift, joylashuv kabi xususiyatlarni belgilaydi.

Misol:

h1 {
  color: blue;
  font-size: 24px;
}

🟠 JavaScript – Interaktivlik (Interaction)

JavaScript – bu veb-sahifaga jon beradi. Tugmalar, modal oynalar, animatsiyalar yaratish va ma’lumotlarni qayta ishlash uchun ishlatiladi.

Misol:

document.querySelector("h1").style.color = "red";

📌 HTML – skelet, CSS – bezak, JavaScript – harakat!

⏭ Keyingi postda "HTML asoslari - dastlabki sahifamiz." yoritiladi.
