UseReducer for Related States in React

🚀 Day 16: Higher-Order Components (HOC) in React A Higher-Order Component (HOC) is a function that takes a component and returns a new enhanced component. 👉 Think of it as: “A wrapper that adds extra functionality to your component” Learn with JavaScript Mastery #ReactJS #FrontendDevelopment #JavaScript #CodingChallenge #LearnInPublic w3schools.com #InterviewPrep

learned optional chaining in react today. making: IPL project 🏏 issue faced: accessing nested objects like "object.object.object" fix/learned: optional chaining ("?.") to avoid crashes & undefined errors small thing, big sanity save. #reactjs #webdev #buildinpublic #javascript

0ms Delay... but what about the extra arguments? 🧐 Most developers know setTimeout(callback, delay), but did you know you can pass arguments directly into the callback? #JavaScript #WebDevelopment #CodingQuiz #SoftwareEngineering #FrontendTips

most React developers don't know why their promises break silently. they wrap everything in .catch() and wonder why errors still slip through. the problem: - .catch() only catches errors up to that point - errors after the chain slip through unhandled - processData() throws but catch doesn't see it the fix : check response status: and one rule: proper error boundaries. check status. validate data. catch at the end. #reactjs #typescript #webdevelopment #buildinpublic #javascript

JavaScript Promise chaining vs async/await: Promise chains: → Harder to read → Error handling complex → Callback-ish Async/await: → Reads like sync code → try/catch works naturally → Easier debugging The choice is obvious. #JavaScript #AsyncJS #CleanCode

JavaScript: Mirror Distance Problem Day 5 👈 Goal: Find the mirror distance of a number — the absolute difference between the number and its reversed form. Approach: Reverse the given number using modulo (%) and division. Subtract the reversed number from the original. Take the absolute value to ensure a positive result. Example: Input: 123 Reversed: 321 Mirror Distance: |123 - 321| = 198 #JavaScript #TypeScript #DSA #CodingInterview #ProblemSolving #FrontendDevelopment #Developers #100DaysOfCode

🤯 Ever wondered why React prints old values? I finally understood stale closures by connecting it with JavaScript closures. Sharing my notes in this carousel 👇 “Slide 8 explains the real problem clearly” #React #JavaScript #FrontendDevelopment

#Elevating React Development: From Basic to Production-Ready #Handling API calls inside "useEffect" is common—but doing it without proper cleanup can lead to memory leaks and unstable behavior. A more professional approach uses AbortController to cancel in-flight requests, ensuring that state updates occur only when components are active. #Why it matters: - Improves application stability - Prevents unnecessary state updates - Enhances overall performance Clean, reliable code is a hallmark of professional development—not just functionality, but responsibility in execution. #ReactJS #FrontendDevelopment #JavaScript #SoftwareEngineering #CleanCode

Most devs reach for a state management library too fast. Before you install Redux or Zustand, try this 👇🏾 // Manage related state together, not separately const [form, setForm] = useState({ name: '', email: '', password: '' }) const handleChange = (e) => { setForm(prev => ({ ...prev, [e.target.name]: e.target.value })) } One state object. One handler. Works for 90% of forms. Stop adding dependencies before you need them. Save this 🔖 #ReactJS #JavaScript #WebDevelopment #Fullstack #CodingTips
