React Learning Journey: Components, JSX, Props, State, and Events

Revisiting React Fundamentals 🚀 Over the past few days, I went back to the core concepts of React to strengthen my foundation. Instead of rushing into advanced libraries, I focused on understanding how React actually works under the hood. Here’s what I’ve revised and practiced so far: 🔹 JSX & component structure Understanding how UI is broken into reusable components and how JSX makes UI logic more readable. 🔹 Props vs State How data flows in React, passing props between components, and managing dynamic UI with useState. 🔹 Event handling Handling user interactions like clicks, inputs, and form submissions in a clean React way. 🔹 Conditional rendering Rendering UI based on conditions (ternary, &&, etc.) to make components dynamic. 🔹 useEffect basics Handling side effects like API calls, timers, and lifecycle behavior with useEffect. 🔹 Basic project structure Organizing folders, separating components, and writing cleaner, scalable code. Why this revisit? I realized strong fundamentals make advanced topics like performance optimization, state management, and full-stack development much easier to grasp. Currently continuing with: ➡️ Building small projects ➡️ Practicing problem solving ➡️ Strengthening JavaScript + React together Always open to feedback and learning from the community.

🚀 Learning and Building with React ⚛️ Hello everyone 👋 Today, I learned some important React concepts and understood clearly what each one is and what it is used for: 🔹 Functional Components – What? -> Functional Components are JavaScript functions that return JSX (UI). -> What for? They are used to create reusable UI parts in a simple and clean way. 🔹 Props – What? -> Props (short for properties) are inputs passed from a parent component to a child component. -> What for? They are used to pass data and make components dynamic and reusable. 🔹 useState – What? -> useState is a React Hook that allows functional components to store and manage state. -> What for? It is used to update and track data like counters, timers, inputs, etc., and re-render the UI when the state changes. 🔹 useEffect – What? -> useEffect is a React Hook used to handle side effects in components. -> What for? It is used for tasks like API calls, timers, subscriptions, and running code when a component mounts, updates, or unmounts. 💡 Hands-on Practice: To apply these concepts, I built: ⏰ Digital Clock – updates time every second using useEffect ⏱ Stopwatch – manages seconds, minutes, and hours using useState and interval logic 📂 Source Code:https://lnkd.in/gq6S_FZD Learning step by step and building real projects to strengthen my foundation 🚀 #ReactJS #LearningAndBuilding #FunctionalComponents #Props #useState #useEffect #FrontendDevelopment #ReactJourney

That one decision changed the way I build frontend applications.

When I first learned React, I thought state was just “A variable that updates the UI” Simple, right? Not really. The confusion starts here: You change state But the UI doesn’t update the way you expect. Or worse: You log the state right after updating it.. And it still shows the old value. That’s when beginners think: “React is weird” But React isn’t weird. State updates are asynchronous. And React re-renders based on state changes, not immediately after setState. Here’s what most people miss 👇 1. State updates are scheduled, not instant. React batches updates for performance. 2. Updating state doesn’t mutate it directly. It creates a new state and triggers re-render. 3. Re-render ≠ DOM update every time. React compares changes first (Virtual DOM). Once I understood this, debugging became easier. React stopped feeling unpredictable. It started feeling structured. The problem wasn’t React. It was my mental model of how state works. Most beginners don’t struggle with syntax. They struggle with how React thinks. And once you understand that — everything changes.

Most students jump into React too early. Yes, I said it. They install: • React • Next.js • 10 npm packages But can’t explain how the DOM works Frontend is not about frameworks. It’s about understanding the foundation: • HTML → Structure • CSS → Layout & Design • JavaScript → Logic & Interaction If you don’t understand: • How the browser renders a page • What the event loop does • How CSS positioning really works • How state changes update the UI Then React will feel like magic. And magic breaks when something goes wrong. When I started focusing on: • Flexbox and Grid deeply • Vanilla JavaScript projects • Building small components from scratch Everything changed. Frameworks stopped being confusing. They became just tools means to an end, not the end itself. If you’re a student learning frontend right now: 1️⃣ Master JavaScript before React 2️⃣ Build 3–5 small projects without frameworks 3️⃣ Learn how APIs actually work 4️⃣ Debug without immediately searching StackOverflow Frontend isn’t about memorizing syntax. It’s about understanding how the browser thinks. And once you get that… You become dangerous (professionally speaking 😉).

🚀 Learning and Building with React ⚛️ 👋 Hello everyone! I’ve recently started learning React, and I wanted to share what I’ve learned so far. 🔹 What is React? React is a JavaScript library used to build fast, interactive, and reusable user interfaces, especially for single-page applications. 🔹 Why use React? ✔ Component-based architecture ✔ Reusable UI components ✔ Faster rendering using Virtual DOM ✔ Easy state and UI management 🔹 Core Concepts I Learned ✅ Components -> Components are the building blocks of a React application. Each component represents a part of the UI. I explored: Class Components ✅ Props (Properties) -> Used to pass data from parent to child components, making components reusable and dynamic. ✅ State -> State is used to store and manage dynamic data inside a component. When state changes, React automatically updates the UI. ✅ Fragments -> Fragments help group multiple elements without adding extra nodes to the DOM. -> Used as <React.Fragment> or shorthand <> </> to keep the DOM clean. 🔹 Hands-on Practice Using these concepts, I built: 🔢 Counter App 🧮 Calculator App 🌙 Dark & Light Mode Toggle 🔗 Source Code👉: https://lnkd.in/gGApYZZW Building these projects helped me understand how React works in real-world scenarios, especially component structure, state management, and UI updates. I’m excited to continue learning React and frontend development 🚀 Open to feedback and suggestions! #React #JavaScript #FrontendDevelopment #LearningReact #WebDevelopment #CodingJourney #ReactProjects
