Top Tweets for #UseCallback
React’te performans konuşulunca #useMemo ve #useCallback çoğu zaman sihirli çözüm gibi anlatılıyor. Gerçekte durum biraz daha dengeli.
React’te her render kötü bir şey değildir. Component’in tekrar çalışması normaldir. Sorun; gereksiz yere pahalı işlemler çalışıyorsa, büyük listeler yeniden hesaplanıyorsa veya memoized child component’lere sürekli yeni referanslar gidiyorsa başlar.
Önemli nokta şu: JavaScript’te object, array ve function’lar referans tipidir.
[] === [] // false
{} === {} // false
Bu yüzden parent component her render’da yeni bir array, object veya callback üretüyorsa bazı child component’ler değişiklik var sanıp tekrar render olabilir.
Burada useMemo ve useCallback yardımcı araçlardır:
• useMemo: Pahalı hesaplamaları tekrar yapmamak veya gerektiğinde stabil bir değer üretmek için
• useCallback: Function referansını korumak gerektiğinde
Ama her yerde kullanmak iyi pratik değildir. Gereksiz kullanıldığında kodu karmaşıklaştırabilir.
Benim React’te seviye atlattığımı hissettiğim nokta şuydu:
“Optimizasyon, hook eklemek değil; state yapısını ve component sınırlarını doğru tasarlamaktır.”

⚛️ React performance — are we overthinking it?
In this Q&A, Faris Aziz explains why some of React’s most commonly used features may actually deserve less attention — not more.
Instead of reaching for #useCallback, #useEffect, and #useMemo by default, developers should focus on writing well-structured code first. React is already pragmatic and performant out of the box, and adding complexity too early can often do more harm than good.
It’s not just about optimization — it’s about knowing when optimization is actually needed.
🔍 Main takeaways:
• Why #useCallback, #useEffect, and #useMemo should be used as little as possible
• How React is already performant without over-optimizing everything
• Why developers should be cautious with manual memoization
• How better code structure leads to cleaner, more reliable React apps

Today I learned the useCallback Hook in React ⚛️
It lets you memoize functions so they don’t get recreated on every render
Useful when passing callbacks to child components to avoid unnecessary re-renders

Using useCallback but forgot to memoize your child component?
React be like: 🤦
✅ Wrap child with React.memo
✅ Pass stable useCallback functions
✅ Ensure props don’t change unnecessarily
Small fix, BIG performance gain.

⚛️ useMemo vs useCallback in React
🔹 useMemo → memoizes value
🔹 useCallback → memoizes function
🧠 Tip:
Use useMemo for expensive calcs,
useCallback to avoid re-creating functions.
