Custom hooks help you extract reusable logic, keep your components clean, and simplify state management. They’re perfect for making your React code more organized and maintainable. Benefits: Reuse logic across components Avoid repetition Simplify complex logic Improve consistency 💡 Pro Tip: Start with small hooks for common patterns—it saves time and makes your projects scalable! #ReactJS #CustomHooks #WebDevelopment #Frontend #JavaScript #CleanCode

🔁 useState vs useReducer — when does structure actually matter? Simple state? useState gets the job done. Complex logic with rules? useReducer keeps things organized and predictable. Swipe through and see the difference in practice 👉 #ReactJS #JavaScript #WebDev #Frontend

Today I want to share an amazing React feature that many developers don't know about. It allows you to create components using a class instead of a function. This gives you access to powerful tools like lifecycle methods, this.state, and this.setState(). 2026 is the new 2016 🤣 #React #JavaScript #Frontend #WebDevelopment #SoftwareEngineering

🚀 Stale Closures Why does state inside setTimeout show old values? Functions capture variables at creation time. If state changes later, the timeout still holds old reference. In OTP flows or retry logic, this creates incorrect behavior. Use functional updates or refs when dealing with async callbacks. #ReactJS #JavaScript #AsyncProgramming #Frontend

Built a Password Generator using React while learning React Hooks in depth. Worked with useState, useEffect, useCallback, and useRef to understand state management, DOM access, and performance optimization in a practical way. #ReactJS #WebDevelopment #Frontend #LearningInPublic #JavaScript

React Closures and State Updates Let’s say we start with: const [value, setValue] = useState(0) Now imagine we run this: setValue(value + 1) setValue(prev => prev + 2) • What is the final value? Now another scenario: setValue(prev => prev + 2) setValue(value + 1) • And now, what is the final value? This happens because React batches updates and functions keep the value they captured earlier. Mixing value + 1 with prev => prev + X can lead to unexpected results. Understanding how React handles state updates makes your code more predictable. What do you think the final values are? #React #JavaScript #Frontend

🚀🚀 Understanding State vs Props: 🔹 Props • Passed from a parent component to a child component • Immutable (read-only) inside the receiving component • Used to configure or pass data to components 🔹 State • Managed within the component itself • Can be updated over time • Used to handle dynamic data and UI changes In simple terms: Props help components communicate, while State helps components manage their own data. Mastering this concept makes it much easier to build clean, predictable, and scalable React applications. 🚀 #reactjs #javascript #frontend #webdevelopment

frameworks and libraries is all about syntax, the real deal is knowing what powers them... useEffect and useState are dangerous syntax to someone who doesn't understand how window loaded and DomContent event listeners work in pure javaScript... Axios is great but if you dont know how the fetch API works, the you would struggle to undertstand how the browser handles http errors... Knowing the fundamentals isn't about going back to the stone age, its what you need to build with confidence. #reactjs #frontend #javaScript

Why useEffect feels unpredictable (but isn’t) Most frustration with useEffect comes from three JavaScript behaviors: 1️⃣ Objects are compared by reference New object → new reference → effect runs again 2️⃣ Functions close over values If you don’t understand closures, dependency arrays feel confusing 3️⃣ State updates are scheduled They don’t run immediately, they’re batched None of this is React magic. It’s "JavaScript". When JS fundamentals are clear, useEffect becomes boring. And boring is good. #reactjs #javascript #frontend #softwareengineering #careeradvice

POV: You install one “small” npm package. Your project: 😌 Your node_modules: 🔥🔥🔥 We don’t install dependencies in JavaScript… We adopt their entire family tree. And somehow we still say, “It’s lightweight.” #JavaScript #ReactJS #NodeJS #WebDevelopment #Frontend #ProgrammingHumor
