JavaScriptni zo'r o'rganmoqchi bo'lsangiz C++ ni o'rganing.
Nega?
1. JavaScript ostida C++ da yozilgan kodlar yotadi.
Hech o’ylab ko’rganmisiz, “setTimeout” o’zi qanday ishlaydi? Uning kodi qanday yozilgan? Yoki “addEventListener” aslida signalni qayerda oladi? Yoki oddiy “<button>” HTML tegi qanday qilib ekranga tugmacha chiqaradi? “Event loop” o’z nomi bilan oddiy “while loop” asosida ishlashini bilarmidingiz?
O’ylab ko’rmagan bo’lsangiz, endi o’ylab ko’ring!
2. Xotirani boshqarish (Memory management)
JavaScript da bu narsani siz qilmaysiz. Sahna ortidagi JS engine bu ishlarni siz uchun qiladi. Uning qanday ishlashini tushunsangiz, quyidagi JS ko’nikmalaringiz rivojlanadi: a. kod optimizatsiyasi b. katta ma’lumotlar bilan ishlash c. “memory-leak“larni payqay olish (ha JS da ham bo’ladi)
3. Multithreading
Bu ham JS da yo’q - desam xato gapirgan bo’laman. Shunchaki JS da boshqacha konstruksiya bor xolos (WebWorker lar). Undan tashqari “event-listener”lar va shu kabi brauzerning asinxron API lari boshqa thread da ishlaydi. Ularni yaxshi tushunish uchun “multithreading” qanday ishlashini bilish foydali.
4. Har bir texnologiya aslida sodda texnologiyalar jamlanmasi ekanini tushunish
Ularning murakkabligi o’sha jamlanmaning kattaligida, ko’pligida. Lupa ostiga olib qarasangiz ularning qanchalik sodda ekanligini ko’rasiz.
P.S. C++ dan tashqari Go, Rust kabi tillarni ham misol qilsam bo’lardi. Lekin ularda memory management bo’yicha qo’shimcha konstruksiyalar kiritilgan. Shu sabab "memory-management"ni yaxshi tushunish uchun C/C++ ga teng kelolmaydi (IMHO).
Undan tashqari eng kuchli JS engine bo’lmish V8 C++ da yozilgan. Chrome ustiga qurilgan har bir brauzerda V8 ishlaydi. NodeJS va Deno ham. Bun ham ancha-muncha C++ kodga ega.

In general, many financial experts support their clients’ desire to buy cryptocurrency, but they don’t recommend it unless clients express interest. “The biggest concern for us is if someone wants to invest in crypto and the investment they choose doesn’t do well, and then all of a sudden they can’t send their kids to college,” says Ian Harvey, a certified financial planner (CFP) in New York City. “Then it wasn’t worth the risk.” The speculative nature of cryptocurrency leads some planners to recommend it for clients’ “side” investments. “Some call it a Vegas account,” says Scott Hammel, a CFP in Dallas. “Let’s keep this away from our real long-term perspective, make sure it doesn’t become too large a portion of your portfolio.” In a very real sense, Bitcoin is like a single stock, and advisors wouldn’t recommend putting a sizable part of your portfolio into any one company. At most, planners suggest putting no more than 1% to 10% into Bitcoin if you’re passionate about it. “If it was one stock, you would never allocate any significant portion of your portfolio to it,” Hammel says.
That strategy is the acquisition of a value-priced company by a growth company. Using the growth company's higher-priced stock for the acquisition can produce outsized revenue and earnings growth. Even better is the use of cash, particularly in a growth period when financial aggressiveness is accepted and even positively viewed.he key public rationale behind this strategy is synergy - the 1+1=3 view. In many cases, synergy does occur and is valuable. However, in other cases, particularly as the strategy gains popularity, it doesn't. Joining two different organizations, workforces and cultures is a challenge. Simply putting two separate organizations together necessarily creates disruptions and conflicts that can undermine both operations.
