Handling Side Effects in React (useEffect) — Before & After While learning React, I faced a common side-effect issue. Calling a function directly inside a component makes it run on every re-render — even when clicking an unrelated button. This leads to unnecessary executions. 🟥 Before callOnce() was triggered on every render (Counter + Data). 🟩 After Using useEffect with a dependency array, the function now runs only when count changes. 💡 This is how useEffect helps us control side effects in React.

At one point, useEffect felt like the answer to almost every problem in React. Over time, I’ve stopped reaching for it by default — here’s why: 🧠 It hides complexity – logic that looks simple often becomes hard to reason about. 🔁 It’s easy to misuse – dependency arrays can introduce subtle bugs and unexpected re-renders. 🧩 Not everything needs an effect – a lot of logic fits better in event handlers, derived state, or custom hooks. 🧼 Cleaner components – fewer effects usually means more predictable and readable code. I still use useEffect when it makes sense — but learning when not to use it made my React code much easier to maintain. #ReactJS #FrontendDevelopment #WebDevelopment #JavaScript #ReactHooks #CodingTips #SoftwareEngineering

🚀 Day 2: Ever wondered how react works internally? 🤔 Today's React learning session was all about react elements! Key Takeaways: ✅ Capitalize names of components you create ✅ Use .jsx for the file where HTML is returned ✅ Custom React library can be created and used. ✅ The render method created a DOM element that appends to the root div. 📹 https://lnkd.in/g43BkyGf 💡 Chrome Extension - https://lnkd.in/gMVMD-mu Following along with Hitesh Choudhary's "Chai aur Code" series continues to be an amazing learning experience! #React #WebDevelopment #LearningInPublic #JavaScript #FrontendDevelopment #ChaiAurCode #Day2

🚀 React Js : Understanding the useEffect Hook The useEffect hook is one of the most important features in React. It allows you to run code after a component renders. 💡 Why useEffect is important: useEffect tells React what should happen after the UI updates. It’s commonly used for tasks like fetching data, updating values, or cleaning up resources. 🧠 How it works: No dependency array → runs after every render Empty dependency array [] → runs only once With dependencies → runs when those values change ✅ Benefits of using useEffect: Cleaner code Better performance Easier to manage side effects Mastering useEffect helps you build more reliable and efficient React applications. 💪 #ReactJS #JavaScript #FrontendDevelopment #ReactHooks #WebDevelopment #Coding

Props > 😉 > Properties👇 📘 Learning React – Props Explained (My Understanding) Today I learned about Props in React, and honestly, this concept makes components feel much more powerful. Props are used to pass data from a parent component to a child component. Instead of hard-coding values, we can send data and make components reusable and dynamic. What I understood: 🔹 Props are read-only 🔹 Data flows one way (parent → child) 🔹 They help customize UI without changing component logic For example, the parent sends a value like a name, and the child simply displays it. Simple idea, but very important for building real apps. Still learning step by step, but props finally make sense 🙌 On to the next React concept 🚀 #LearningReact #ReactJS #FrontendJourney #WebDevelopment #JavaScript #Props

I’ve been learning React for a while. Small projects, big lessons—here’s what I learned from a recent mini challenge. Instead of just watching tutorials, I’m focusing on small, practical projects that help me strengthen the basics. This Profile Card mini challenge was one of those, and it helped me work on: - Structuring React components better - Getting more comfortable with props - Writing cleaner JSX - Organizing a simple React project This mini challenge was inspired by a React course by Jonas Schmedtmann. (I mostly followed the styling from the challenge, focusing on building the React functionality first.) It’s a small project, but it shows steady progress—and that’s the goal. I’ll share updates when I can and keep building in the meantime.
