1. useState nima?

useState bu Reactda foydalaniladigan xotira (yoki holat). Ya’ni:

🔄 "O'zgaruvchini saqlab turadigan va uni o'zgartirganda sahifani avtomatik yangilaydigan" maxsus funksiya.

Oddiy JavaScriptda o‘zgaruvchi shunaqa:

let sana = 5;


Reactda esa bunday qilamiz:

const [sana, setSana] = React.useState(5);

Bu degani:

sana — bu o‘zgaruvchimiz.

setSana — bu funksiyamiz, sanani yangilaydi.

useState(5) — boshlang‘ich qiymat, hozir sana = 5.

ViteConf 2024 was a blast

The third edition of ViteConf was another incredible community party. ViteConf 24 showed how much the Vite Ecosystem keeps growing and evolving.

int myAge = 25;
int* ptr = &myAge;

printf("Qiymat: %d\n", myAge); // 25
printf("Manzil: %p\n", &myAge); // 0x... (xotira manzili)
printf("Pointer ichidagi qiymat: %p\n", ptr); // ptr o‘zida myAge'ning manzilini saqlaydi
printf("Pointer orqali o‘qilgan qiymat: %d\n", *ptr); // 25 – ptr orqali qiymatga kiriladi

🤩 Bruno: An IDE for Exploring and Testing HTTP APIs

An open source (though a commercial version is available) Node and Electron-based desktop app for crafting and testing HTTP requests, complex and simple. Think of it as a lightweight alternative to something like Postman.
