Day 5 - 📝 Understanding Forms in HTML Forms are one of the most important parts of web development. They allow websites to collect user input and interact with users effectively. From login pages to feedback forms, HTML forms make communication between users and websites possible. ➡️Common HTML Form Elements ✔ <form> – Creates the form structure ✔ <input> – Accepts user data (text, email, password, etc.) ✔ <label> – Describes input fields ✔ <textarea> – Multi-line text input ✔ <select> & <option> – Dropdown lists ✔ <button> – Submits or triggers actions ➡️Why Forms Matter ✅ Used in registrations and login systems ✅ Collect feedback and survey responses ✅ Enable searches and data submissions ✅ Essential for dynamic and interactive websites Learning how forms work is a fundamental step toward becoming a skilled frontend developer. #HTML #WebDevelopment #Frontend #Coding #LearningToCode #100DaysOfCode

Hello, Tech Wizards 👋 🚀 Scenario-Based React & JavaScript Q&A (Real-World Edition) 🔥 1) Scenario: Component re-renders again and again Q: Why is this happening? A: Inline functions/objects change reference on every render. ✅ Fix: useCallback, useMemo, React.memo 🧠 ⚡ 2) Scenario: API response updates old screen after fast navigation Q: How to stop stale data? A: Cancel previous API calls using AbortController or track calls via useRef ⛔ 📦 3) Scenario: 10,000 items list freezes UI Q: How do big apps handle this? A: Use list virtualization (react-window, react-virtualized) 🚀 🧮 4) Scenario: Counter gives wrong value on rapid clicks Q: What’s the mistake? A: Using direct state update. ✅ Correct: setCount(prev => prev + 1) 🔁 🧵 5) Scenario: Props drilling across 5 components Q: Context or Redux? A: Context for static data (theme, auth). Redux/Zustand for frequent updates ⚖️ 🧠 6) Scenario: useEffect runs infinitely Q: Why? A: Missing or incorrect dependency array. ✅ Always list external values used inside useEffect 📌 ⏳ 7) Scenario: Heavy computation slows rendering Q: How to optimize? A: Wrap calculation in useMemo to avoid re-computation 💡 🔄 8) Scenario: Child component re-renders when parent state changes Q: Even if props didn’t change — why? A: New function references passed as props. ✅ Fix with useCallback 🎯 🧪 9) Scenario: console.log(state) shows old value after setState Q: Bug? A: No. State updates are async & batched ⏱️ Use useEffect to track updated value. 🌐 10) Scenario: Need global loading & error handling for APIs Q: Best practice? A: Use React Query / SWR for caching, retries, and background sync 🔥 happy coding and keep smiling 😊 #ReactJS #JavaScript #FrontendInterview #WebDevelopment #ReactDeveloper #opentowork

💥Just hit a milestone on my personal portfolio project — and I wanted to share what building it has taught me so far. As someone still early in my journey as a developer, this project has been more than just writing code🙂↕️. It's been a crash course in turning concepts into real, working products. Here's what I've taken away so far: ✅ Component Architecture — Breaking down a UI into reusable React components (About, Skills, Experience, Contact) taught me how to think in systems, not just screens. ✅ Third-party Integrations — Wiring up EmailJS to handle form submissions showed me how to connect a frontend to real-world services without a backend, and how to handle both success and error states gracefully. ✅ UI/UX Thinking — Working with "Tailwind CSS" and "react-parallax-tilt" pushed me to think beyond functionality. ✅ State Management — Managing form state, toast notifications, and conditional rendering helped me get more comfortable with React hooks like useState and useRef in practical scenarios. ✅ Attention to Detail — From gradient clipping to border glow effects, I learned that the small visual touches are what separate a decent project from a great one. 🫠 This portfolio is still a work in progress — but that's exactly the point. Every commit is a lesson. what I learnt? just start. You'll learn more from shipping imperfect code than from waiting until you feel "ready." #ReactJS #TailwindCSS #WebDevelopment #FrontendDevelopment #LearningInPublic #PortfolioProject #JavaScript #OpenToWork

📘 Day 79: JavaScript DOM Basics 🔹 DOM (Document Object Model) is a tree-structured programming representation of an HTML document. 🔹 It allows JavaScript to access, modify, add, or delete HTML elements, content, attributes, and styles dynamically. 🔹 DOM converts static HTML into a dynamic and interactive web page. 🔹 What we can do using DOM: Select HTML elements Change text and content Modify CSS styles Add or remove HTML elements Handle events (click, input, etc.) 🔹 innerHTML Used to get or set the content inside an HTML element. 🔹 getElementById() Selects one element using its unique ID. 🔹 getElementsByClassName() Selects multiple elements with the same class name. Access elements using index numbers. 🔹 getElementsByTagName() Selects elements by their tag name. Also returns a collection, so index is required. 📌 The DOM is the foundation for building dynamic, interactive, and responsive websites 🚀 #JavaScript #Day79 #DOM #WebDevelopment #Frontend #JSBasics #CodeJourney #FasluRahman #OpenToWork

🌦️ Leveling up my Frontend skills: Building a Modern Weather App Excited to share my latest project! I built a fully functional Weather Application using Vanilla JavaScript and the OpenWeatherMap API. While the concept is classic, I pushed myself to modernize the UI and improve the UX. I implemented a Glassmorphism design (frosted glass effect) using advanced CSS backdrop-filters to give it a sleek, 2026 look. 🚀 Key Technical Features: Asynchronous JavaScript: Used async/await for efficient data fetching. Dynamic DOM Manipulation: Real-time updates for temperature, humidity, and wind speed. Error Handling: User-friendly alerts for invalid city names. UX Improvements: Added "Enter" key support and dynamic background/icons based on weather conditions. It was a great challenge to refine the code structure and focus on clean, readable JavaScript. 🔗 Source Code (GitHub): [https://lnkd.in/d7UJgbGw] 🎥 Demo: Check out the video below!

Most people learn JavaScript. Few truly understand the DOM. The Document Object Model (DOM) is what turns static HTML into interactive web applications. If you understand DOM deeply, you understand: • How browsers render pages • How event handling really works • How dynamic UI updates happen • How frameworks like React manipulate the virtual DOM • Why performance issues occur Core DOM concepts every developer should master: 🔹 Element selection (getElementById, getElementsByTagName) 🔹 Creating & modifying nodes (createElement, appendChild) 🔹 Event handling (addEventListener) 🔹 Mouse, keyboard & form events 🔹 Parent-child node relationships Frontend interviews often test this indirectly. Because if you understand the DOM, you understand how the web works. Frameworks change. Browser fundamentals don’t. Master the foundation. 🚀 #JavaScript #FrontendDevelopment #WebDevelopment #DOM #SoftwareEngineering #FullStackDeveloper #ReactJS #CodingInterview #TechCareers #Hiring #OpenToWork #100DaysOfCode
