Хаммамиз биламизки phpda websaytning backend qismini yozish mumkun. Lekin JS yordamida ham websaytning backend (orqa tomoni) ni yani NodeJS da qilish mumkun bo`lmoqda.
Men o`z bilgan o`rganganlarimni sizlar osonroq o`rganishingiz uchun yozib bormoqchiman. Kerakli bo`lsa faqatgina post va mavzuga + tugmasini bossangiz kifoya.
Bu mavzuda u qanday, bu qanday ishlaydi, nega bunaqa, va boshqacha postlar kerakmas. Kodlarni xohlagan odam yozishi mumkun. Faqat savol va javoblarsiz.

kodlarni yozganda bazida tushuntrishim bazida tushuntirmasligim mumkun, unutmang yozgan kodimni asosan o`zim osonroq topish uchun yozmoqdaman, tushuntirishga majbur emasman. Shunday ekan savol bermang.


Унутманг бу сизга пулини тўлаб қўйган пуллик курсингиз эмас.
