PSFree version 1.5.0 includes the Lapse kernel exploit for PS4 firmware 9.00, offering a fast and reliable way to gain deeper system access, though it may cause crashes and is still about 50% stable. It uses a payload loader that can be customized, and the project is open for contributions. This exploit is part of a chain combining webkit and kernel exploits to enable jailbreaking, which allows running custom software on PS4 and potentially PS5. Using PSFree can help you unlock more control over your console, but it requires caution and restarts if errors occur, as it is still in beta. This can benefit users wanting to explore homebrew or custom firmware on supported PS4 versions[1][2][5].

JavaScriptdainstanceof operatori
JavaScriptda instanceof operatori bu objectni malum bir Sinf yoki Konstruktorninng prototip zanjirida borligini aniqlash uchun ishlatiladi.
obj instanceof Constructor
obj ni Constructor prototip zanjirida bor yo'qligiga qarab true yoki false qaytaradi.
Misollar:
class Person {}
const person1 = new Person()
console.log(person1 instanceof Person); // true
console.log(person1 instanceof Object); // true
const arr = [1, 2, 3]
console.log(arr instanceof Array); // true
console.log(arr instanceof Object); // true
JavaScriptda Arrayning prototipi Objectga borgani uchun bu misolda true qaytaryabdi.
❗️Instanceof faqat object va ularning prototip zanjiridan tekshirganligi uchun, buni Primitivelar bilan ishlatib bo'lmaydi.
✅ TypeScript narrowingda Instanceof dan keng foydalanish mumkin.

JavaScriptda o'zining tayyor metodlaridan foydalanish (Reduce methodi).
JavaScript bizga o'zining ko'plab tayyor metodlari taklif qiladi. Ularni ishlatish orqali biz dastur kodimizni soddaroq ko'rinishga olib kelishimiz mumkin. Ulardan biri Arrayning reduce methodi.
Bizga products degan state bo'lib unda mahsulotlarning nomi, narxi va shunga o'xshash malumotlari list ko'rinishida saqlanayotgan bo'lsin. Loyihada o'sha listdagi barcha mahsulotlarning umumiy narxini qaytarish kerak bo'lib qolsa. Uni for loopi va reduce methodi bilan quyidagicha amalga oshirishimiz mumkin.
For orqali:
let prices = 0;
for(let i = 0 ; i < state.products.length ; i++){
prices = prices + state.products[i];
}
Reduce orqali:
let prices = state.products.reduce((acc,product)=> acc + product.price,0)
Ko'rganimizdek Reduce bilan dastur kodi soddaroq ko'rinishga keldi. Lekin shuni ham hisobga olib ketish kerak for loopi reduce qaraganda tez ishlashdi.
