Unlearning Web Dev Norms: From jQuery to Vite

🚀 ReactJS Cheat Sheet – Save this for later! If you're working with React or just getting started, here’s a quick and practical breakdown 👇 ⚛️ Components & JSX Think of components as building blocks. JSX lets you write HTML-like code inside JavaScript. 🔁 Props & State Props = data passed from parent State = data managed inside component 🪝 Essential Hooks useState → manage state useEffect → side effects useRef → DOM access useMemo/useCallback → performance boost 🖱️ Events & Handlers Handling clicks, inputs & user actions is super simple with functions. 🔀 Conditional Rendering Show UI based on conditions using ternary operators or logical && 📋 Lists & Keys Render lists with `.map()` and always use unique keys! ⚡ Performance Optimization Avoid unnecessary re-renders with memoization & efficient state updates. 📌 Quick Tip: Keep components small, reusable & clean! --- 💡 Save this post for revision & share with your dev friends! #ReactJS #WebDevelopment #Frontend #JavaScript #CodingTips #100DaysOfCode #Developers #Tech #Programming #ReactDeveloper #LearnToCode 🚀

🚀 JavaScript Array Methods Cheat Sheet 🚀 Level up your JS game (especially in React!) with these essentials. Simple explanations + examples: • filter() 🔍: New array of matching items. numbers.filter(n => n > 5) → • map() ✨: Transform every item. names.map(name => name.toUpperCase()) → ["ALICE", "BOB"] • find() 🕵️: First match only. users.find(u => u.id === 1) • findIndex() 📍: Index of first match. • every() ✅: All true? scores.every(s => s > 60) → true/false • some() ➕: At least one true? • fill() 🧱: Fill with a value (mutates!). • concat() 🔗: Merge arrays safely. Pro Tip: Chain filter + map in React for clean lists! data.filter(item => item.active).map(item => <Item key={item.id} />) Master these = faster code + happier teams. 💪 #JavaScript #React #WebDev #CodingTips #Frontend #ArrayMethods #Developers #Programming #ReactJS #30DaysOfCode

If you’re learning frontend development, focus on this: Not 100 tools. Just these 5 👇 1. HTML 2. CSS 3. JavaScript 4. React 5. Git & GitHub That’s it. Stop jumping between technologies. Depth > Breadth Master these and you’re ahead of 90% beginners #webdev #frontenddeveloper #codingtips

how do you usually study new courses? i’ve been building a project alongside it + keeping notes in the same file (above+below the code) works for me so far, but it’s starting to get a bit cluttered 😬 curious if anyone has a better system #webdevelopment #frontend #reactjs #javascript

🧠 JavaScript Closures (without overcomplicating it) Most developers use them… few actually understand them. A closure is when a function “remembers” the variables from where it was created, even after that scope is gone. Simple idea: You create a function inside another one The inner function still has access to the outer variables Even after the outer function has finished executing 👉 Sounds simple, but this unlocks powerful patterns. Now here’s the real insight: If you use React, you rely on this EVERY SINGLE DAY. Hooks like useState and useEffect are built on top of closures. That’s how React “remembers” state between renders Without using classes So in practice: 👉 Understanding closures = understanding React at a deeper level #javascript #reactjs #frontend #webdevelopment #programming

Props vs State in React Most beginners get confused between Props and State in React. At first, both seem similar because both store data. But the real difference is simple: * Props = Data received from another component * State = Data managed inside the component Example: function Parent() { return <Child name="Durgesh" />; } function Child(props) { return <h1>{props.name}</h1>; } Here, `name` is a prop because it comes from the Parent component. Now look at State: const [count, setCount] = useState(0); Here, `count` is managed inside the same component. Quick Difference 👇 • Props are read-only • State can be updated • Props come from parent to child • State belongs to the component itself Think like this: Props = Things you receive State = Things you control Once you understand this difference, React becomes much easier.
