🚀 React Series – Day 12 useCallback – Preventing Unnecessary Function Re-creation In React, functions are re-created on every render by default. In many cases this is fine, but when passing functions to child components, it can cause unnecessary re-renders. The useCallback hook helps by memoizing functions - so the same function instance is reused unless dependencies change. This is especially useful when working with optimized components (like memoized ones). 👉 In simple terms: • useMemo → memoizes values • useCallback → memoizes functions Used together, they help keep applications efficient and performant. #reactjs #javascript #frontenddeveloper #webdevelopment #codinginterview #learnreact #30daysofcode #programming #reactinterview #react #coding

3 React hooks you should use more often: 🔹 useMemo Caches expensive calculations. Recalculates only when dependencies change. 🔹 useCallback Caches a function reference. Prevents unnecessary re-renders in child components. 🔹 useReducer Better than useState for complex state logic. Think of it as a mini Redux. Most devs only use useState and useEffect. The ones above can make a real difference. 🎯 #ReactJS #Frontend #JavaScript #WebDev #Programming

🧠 JavaScript Closures (without overcomplicating it) Most developers use them… few actually understand them. A closure is when a function “remembers” the variables from where it was created, even after that scope is gone. Simple idea: You create a function inside another one The inner function still has access to the outer variables Even after the outer function has finished executing 👉 Sounds simple, but this unlocks powerful patterns. Now here’s the real insight: If you use React, you rely on this EVERY SINGLE DAY. Hooks like useState and useEffect are built on top of closures. That’s how React “remembers” state between renders Without using classes So in practice: 👉 Understanding closures = understanding React at a deeper level #javascript #reactjs #frontend #webdevelopment #programming
