Namaskar dosto!

Lekin agar aap beginner ho aur aapke dimaag mein yeh confusion hai ki:
- JavaScript kya hoti hai?

To yeh article aapke liye hai. Yahan hum JavaScript ko simple Hinglish style mein samjhayenge.
JavaScript Kya Hai?
JavaScript ek programming language hai jo web pages ko interactive banati hai. Jab aap kisi website par form fill karte ho, button click karte ho, ya bina page reload kiye kuch animation dekhte ho, to wo sab JavaScript ki wajah se hota hai.
JavaScript ko 1995 mein Brendan Eich ne banaya tha. Ye language HTML aur CSS ke saath milkar kaam karti hai:
- HTML: Page ka structure batata hai
- CSS: Page ko design karta hai
- JavaScript: Page mein interactivity laata hai
JavaScript Ka Use Kya Hai?
JavaScript ka use lagbhag har website mein hota hai. Kuch common examples:
- Button click hone par message dikhana
- Form validation lagana
- Image sliders aur carousels banana
- Search suggestions dikhana
- Popups open ya close karna
- Animations, games, ya interactive features banana
Aaj ke time mein Google, Facebook, YouTube, Instagram jaise bade websites bhi JavaScript extensively use karte hain.
JavaScript Kaise Kaam Karti Hai?
JavaScript browser ke andar hi chalti hai, jahan ek special engine usse run karta hai:
- Chrome: V8 Engine
- Firefox: SpiderMonkey
Aap JavaScript ka code <script> tag ke andar likh kar HTML file mein use kar sakte ho. Jaise:
<script>
alert("Hello JavaScript World!");
</script>
Yeh browser ko batata hai ki is block ke andar JavaScript code hai.
Java vs JavaScript – Confuse Mat Ho
Bahut log soch lete hain ki Java aur JavaScript ek hi language hain. Lekin yeh dono alag languages hain.
| Java | JavaScript |
|---|---|
| Compile hoti hai | Browser me run hoti hai |

| Strictly typed | Loosely typed |
Naam milta-julta hai, lekin kaam bilkul alag hai.
