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. #javascript ☑️@valisherbotirov

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. #javascript ☑️@valisherbotirov
