💡 Handling Click Events in React In React, user interactions like button clicks are handled using onClick events. 👉 onClick triggers a function 👉 Function updates state or performs an action 👉 UI updates automatically 📌 Common Uses: • Button actions • Form submissions • Toggle features • Navigation triggers • Dynamic UI updates ⚡ React uses camelCase event naming Example → onClick (not onclick) Master event handling to build interactive React apps.

🚀 React Series - Day 3 State - The Reason React Apps Feel Alive Static UI is boring - users expect interaction. That’s where state comes in. State allows components to store data that can change over time, such as: • Button clicks • Form inputs • Toggle switches Whenever state changes, React automatically updates the UI. This is what makes React applications feel dynamic and responsive. 👉 In modern React, state is usually managed using the useState hook. #reactjs #javascript #frontenddeveloper #webdevelopment #codinginterview #learnreact #30daysofcode #programming #reactinterview #react #coding

⚛️ Struggling with unexpected bugs in React? Chances are… it’s your useEffect 👀 useEffect is powerful — but only when used correctly. Here’s what every React developer should know: 🔹 Runs After Render It executes after every render (unless controlled properly). 🔹 Dependency Array Matters Missing dependencies = bugs Too many dependencies = unnecessary re-renders 🔹 Perfect for Side Effects API calls 🌐, event listeners 🎧, timers ⏱️ — all handled here. 🔹 Cleanup is Important Avoid memory leaks by returning a cleanup function. 🔹 Don’t Overuse It Not everything needs useEffect. Keep logic simple. 👉 Mastering useEffect = cleaner & bug-free apps. 🚀 Keep learning.

Choosing between Context API, Redux, and Zustand isn’t about preference… It’s about understanding the problem you’re solving. 🚫🫧 Most devs skip this—and end up overengineering their apps. Your state management choice can either: 🚀 Keep your app simple and scalable. or 💀 Turn it into a debugging nightmare. 🔖 Save this post & find the list below Follow me: - Parthib M. 🐺 to explore more updates on Web Development. #WebDevelopment #ReactJS #JavaScript #StateManagement #Redux #ContextAPI #Zustand #FrontendDevelopment #Programming #Developers #TechCommunity #BuildInPublic #100DaysOfCode

⚛️ Common React Mistakes That Are Killing Your Performance 💀 You think your React code is fine… . But these small mistakes are silently breaking your app 👀 Here’s what most developers still do wrong 👇 . ❌ Mutating state directly React won’t re-render properly (page 2)  ❌ Using index as key Leads to weird UI bugs when list updates (page 3)  ❌ Too much global state Unnecessary re-renders & messy logic (page 4)  ❌ useEffect misuse Missing dependency array = infinite loop 🔁 (page 5)  ❌ Storing derived state You’re duplicating logic for no reason (page 6)  ❌ Too many re-renders New objects/functions every render = performance drop (page 7)  ❌ Ignoring loading & error states Your UI breaks when API fails (page 8)  ❌ Poor folder structure Good code needs good organization (page 9)  . 🔥 React isn’t hard… Bad practices make it hard 💬 Clean code = scalable apps 📌 Save this before your next project .

JavaScript is single-threaded. But your app behaves like it’s not. Here’s the illusion 👇 You use: → Promises → setTimeout → async/await And it feels concurrent. But actually: → Tasks are queued → Event loop processes them Problem: If one task is heavy: ❌ Everything waits Result: → UI lag → API delay Key insight: Async doesn’t mean parallel. It means scheduled. Understanding the event loop is key to performance. #JavaScript #EventLoop #Frontend #Backend #Performance #SoftwareEngineering #Engineering #Programming #Tech

🚀 React Series - Day 5 useEffect - Making React Work with the Outside World Not everything in an app is just UI rendering. Sometimes you need to: • Fetch data from APIs • Run logic after rendering • Set up timers or listeners This is where useEffect is used. It runs after a component renders and allows you to handle these “side effects” cleanly. With the dependency array, you can control when it runs: • Empty array → runs once • With values → runs when those values change 👉 It’s a key concept for handling real-world app behavior in React. #reactjs #javascript #frontenddeveloper #webdevelopment #codinginterview #learnreact #30daysofcode #programming #reactinterview #react #coding

Code doesn’t run by itself. Something runs it for you. 👉 That “something” is called a runtime. It’s the layer between your code and your system. It handles: - Execution - Memory - Communication with the system You don’t see it. But it’s always there. Examples: - Your browser runs JavaScript - Node.js runs backend code - Android runtime runs apps Without a runtime… your code is just text. You click → runtime executes → you see result.

Stop Guessing, Start Coding: The useEffect Cheat Sheet! 🚀 Ever wondered why your React component is re-rendering infinitely? Or why your API call isn't triggering when it should? The useEffect hook is the "heartbeat" of React functional components, but it’s also where most bugs live if the Dependency Array isn't handled correctly. I put together this visual guide to simplify how useEffect behaves in 3 common scenarios: 🔹 No Array: Runs on every single render (Handle with care! ⚠️) 🔹 Empty Array []: Runs once when the component mounts (Perfect for initial data fetching). 🔹 With Variables [count]: Runs only when that specific state or prop changes. Pro Tip: Always use a Cleanup Function (like clearInterval) to keep your app’s memory usage healthy! 🧹 Check out the image below for a quick reference you can save for your next project. 📖 Which React Hook should I break down next?
