🔥 Оптимизируй React-компоненты с помощью useDeferredValue

Если у тебя есть input, фильтрация, поиск или ререндер списков — не спеши лепить useMemo и useCallback. Сначала попробуй useDeferredValue:


const deferredQuery = useDeferredValue(query);
const filtered = useMemo(() => filterData(data, deferredQuery), [deferredQuery]);


📌 Что делает?
useDeferredValue говорит React: "не срочно, можно чуть позже"
— идеально для плавности UI без блокировок при частых обновлениях.

🧠 Кейс:
Пользователь быстро вводит текст → React не тормозит от ререндеров больших списков → всё работает плавно и отзывчиво.

⚠️ Но не путай с debounce:
- debounce — задержка до начала работы
- useDeferredValue — отложенный рендер результата

Mr. Durov launched Telegram in late 2013 with his brother, Nikolai, just months before he was pushed out of VK, the Russian social-media platform he founded. Mr. Durov pitched his new app—funded with the proceeds from the VK sale—less as a business than as a way for people to send messages while avoiding government surveillance and censorship.

Should You Buy Bitcoin?

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.
