That's it, I'm not using neither #React nor #NextJS again.
Fuck your #vulnerabilities, fuck your #framework, fuck you fuck you fuck you.

Khi viết React với arrow function, bạn chọn **implicit** hay **explicit return**?
- **Implicit**: Ngắn gọn, đẹp mắt, phù hợp component đơn giản.
- **Explicit**: Rõ ràng, dễ debug, cần thiết khi có logic.
Lạm dụng implicit để "ngắn" có thể khiến code khó đọc. Dùng explicit máy móc cũng gây dư thừa.
Cá nhân tôi ưu tiên **readability > brevity**. Dùng implicit mặc định, chuyển explicit khi cần.

React-vulnerability notifications is the new black friday/week/cyber monday notifications Hellscape.
Seriously though, I'm glad to receive vulnerability notifications. I can't say the same about receiving spam.
