React Hooks: useState vs useEffect

What is useEffect in React? 🤔 Before useEffect, side effects like API calls, subscriptions, or DOM updates could easily become messy and hard to manage. With useEffect, React gives us a clean and predictable way to handle side effects: ✅ Fetch data ✅ Sync with external systems ✅ Run logic after render ✅ Clean up when needed It helps keep components organized, readable, and maintainable. #React #ReactJS #JavaScript #WebDevelopment #Frontend #FrontendDevelopment #ReactHooks #useEffect #UIDevelopment #WebDeveloper #FrontendEngineer #Coding #Programming #SoftwareDevelopment #Tech #LearnReact #DevCommunity

Session 75 Covered | Cohort 2.0 **********TASK 5(React.js): User Generator with Remove Functionality********** In this session, I built a user generator app in React.js with a remove feature, focusing on clean state management and component structure. What I learned 👇 🖱️ Created a form with 4 inputs using two-way binding via useState 🖱️ Handled form submission with a formHandler and preventDefault() 🖱️ Managed users using an array state allUsers 🖱️ Added new users without mutating state using the spread operator 🖱️ Built a separate Card component and rendered it using allUsers.map() 🖱️ Implemented remove functionality by copying the state array, removing the selected index, and updating state A simple project, but it covered multiple core React concepts working together.

👋 Hey LinkedIn fam! Today I learned about the useEffect Hook in React, one of the most important hooks for handling side effects in functional components ⚛️ 🔍 What useEffect does: It runs code when something happens in a component — like when it mounts, updates, or unmounts. 🧠 Common uses: Fetching data from APIs Updating the DOM Setting up event listeners Cleanup tasks (like removing listeners or timers) 📌 Simple idea: useEffect(() => { ... }, [dependencies]) Empty dependency → runs once With dependencies → runs when values change It’s amazing how useEffect helps control component lifecycle without writing class components 🚀 #ReactJS #UseEffect #FrontendDevelopment #WebDevelopment #LearningJourney #JavaScript

🚨 React Devs: This tiny thing controls your entire useEffect behavior 👀 useEffect is one of the most powerful hooks in React. The behavior of useEffect depends entirely on its dependency array. Here are the 3 most important ways to use it 👇 1️⃣ No Dependency Array useEffect(() => { // runs on every render }); 🔹 Executes after every render 2️⃣ Empty Dependency Array [] useEffect(() => { // runs only once }, []); 🔹 Runs only on initial render 🔹 Used for: API calls Initial setup Event listeners 3️⃣ With Dependencies [state/props] useEffect(() => { // runs when count changes }, [count]); 🔹 Runs when dependency value changes 🔹 Keeps effects in sync with state or props ✅ Best Practice Tips Always include all used variables in dependencies Avoid unnecessary re-renders Think of useEffect as: “React, do this when something changes.” Understanding dependencies = mastering React side effects 💡 #ReactJS #JavaScript #FrontendDevelopment #WebDevelopment #useEffect #ReactHooks #Coding #FullStackDeveloper #BackendDevelope

I thought I knew useEffect… until I actually used it in real projects. * Studying useEffect in tutorials is one thing, seeing it run in real projects is another. * When I first studied useEffect, I understood the rules, but seeing it in real projects is what really made it stick. * Things like: • When to run an effect • How dependency arrays control behavior • When cleanup is needed (like intervals!) * These small details change how predictable your components are and make debugging so much easier.

🚀 Continuing my React learning journey… Today I explored one of the most important React hooks — useEffect() It helps handle side effects like: ✔ API calls ✔ Event listeners & timers ✔ Component lifecycle behavior ✔ Updating DOM 🔑 Dependency Array = Control [] → runs once on mount [state/props] → runs only when data changes No array → runs on every render Learning useEffect isn’t just about syntax—it’s about understanding when code runs, why it runs, and how to keep React apps performant and reliable. One hook at a time, building better frontend skills 🚀 #ReactJS #ReactHooks #FrontendDevelopment #JavaScript #LearningReact #WebDeveloper #ContinuousLearning

A Clean React.js Folder Structure = Cleaner Code & Smoother Development. Every React project becomes easier to scale when your folders are organized from day one. Clear structure means fewer bugs, faster debugging, and more time to focus on building real features. This cheatsheet breaks down how you can structure components, hooks, pages, services, assets, and utils in a way that keeps your project tidy and future-proof.
