Day 16 – JavaScript Challenge Built a Star Rating component using React, focusing on user interaction and state-driven UI updates. This project helped me understand how dynamic components respond to user actions in real time. What I implemented: *Interactive star rating system *Hover and click-based UI behavior *State management using React hooks *Reusable and scalable component design Step by step, these projects are strengthening my React fundamentals and confidence in building real-world UI components. #ReactJS #JavaScript #FrontendDevelopment #WebDevelopment #ReactHooks #UIComponents #100DaysOfCode #DeveloperJourney

⚛️ React Props vs State – A Quick Breakdown Both props and state help manage data in React, but they have different roles. Props are used to pass data from parent to child components and are read-only. State is used to manage data inside a component and can change over time, triggering re-renders. 👉 Use props for configuration and data flow 👉 Use state for dynamic and interactive UI Mastering this concept is essential for writing clean, scalable React applications 🚀 #ReactJS #FrontendDevelopment #TailwindCSS #JavaScript #ReactBasics #WebDev #W3School

🚀 Mastering the DOM in JavaScript! Here’s a quick cheat sheet I use to recall essential DOM methods and events while building dynamic web apps using React (and the entire MERN stack) 💻 Understanding the DOM is the backbone of frontend development whether it’s handling user interactions, updating UI efficiently, or manipulating elements directly when needed. 📘 Key DOM Concepts Covered: Selecting elements dynamically Creating & modifying nodes Handling events (Mouse, Keyboard, Form) 💡 DOM mastery = Smoother React logic + Better debugging + Cleaner component rendering #JavaScript #MERNStack #FrontendDevelopment #WebDevelopment #ReactJS #DeveloperLearning #CodingCheatSheet #TechCareer

Built a Toast Notification System using JavaScript & React I recently created a custom toast notification system that allows messages to appear on different screen positions with an automatic timer. Features: ✅ Display toasts on all sides (top / bottom – left / right) ✅ Auto-dismiss with configurable timer ✅ Clean and reusable component structure ✅ Smooth user experience This project helped me understand: • state management • handling timers properly • dynamic UI rendering • building reusable components Live demo 👇 🔗 https://lnkd.in/gSBjhReu Small UI features like toast notifications may look simple, but they play a huge role in real-world applications. Always learning by building 💻🔥 #JavaScript #ReactJS #FrontendDevelopment #WebDeveloper #Learning #MERN #Projects

React Calculator Project ⚛️ Built a calculator using React functional components and hooks. Focused on onClick event handling, state management, and handling edge cases like division by zero, with a clean and simple UI. 🔗 GitHub: https://lnkd.in/dWfHCAyZ #ReactJS #JavaScript #FrontendDevelopment #Projects #Learning

Day 15 – JavaScript Challenge ✅ Built a Random Color Generator using React, allowing users to generate HEX, RGB, and random colors dynamically. This project helped me practice JavaScript logic while applying React concepts for real-time UI updates. Key highlights: *Random color generation logic (HEX & RGB) *Dynamic background color updates *State management using React hooks *Clean and interactive UI Small projects like this are helping me connect JavaScript fundamentals with modern React development. #ReactJS #JavaScript #FrontendDevelopment #WebDevelopment #ReactHooks #UIProjects #100DaysOfCode #DeveloperJourney

🚀 React User Form Project Built a User Form using React to practice controlled components and state management. ✨ Key Features: Used useState to manage form inputs Real-time data preview Input validation (name without numbers, phone number handling) Checkbox state management Clean UI with CSS Flexbox This project helped me strengthen my understanding of React hooks, form handling, and component structure. 🔧 Tech Stack: React | JavaScript | CSS #ReactJS #WebDevelopment #Frontend #JavaScript #LearningByDoing

💡 JavaScript Concept Every Developer Should Know: Event Delegation Suppose you want to add the same event to multiple similar elements. The most straightforward approach would be to attach an event listener to each element individually. ⚠ Problems with this approach: Multiple event listeners Poor scalability Not ideal for dynamic UI updates 👉 This is where Event Delegation comes into play. 🔹 What is Event Delegation? Event Delegation is a pattern to handle events efficiently. Instead of attaching an event listener to every child element, we attach a single event listener to a parent element and use the event.target property to identify which child triggered the event. ✔ Why this is better: Only one event listener Works for dynamically added elements Better performance & memory usage Cleaner and more scalable code #JavaScript #JSConcepts #EventDelegation #WebDevelopment #FrontendDevelopment #JavaScriptInterview #LearnJavaScript #Developers #InterviewQuestion #ReactJS

🚀 Event Handling in React JS – Explained Simply (with Examples) Event handling is one of the most important concepts in React. It allows users to interact with your UI—like clicking a button, submitting a form, or typing in an input—and trigger logic behind the scenes. 🔹 What is Event Handling in React? Event handling in React is how we respond to user actions (events) such as onClick, onChange, onSubmit, etc. React uses camelCase syntax for events and passes functions, not strings. 🔹 Common Mistake: Function Call vs Function Reference explained :as small mistakes leads to big issues 🔹 Key Points to Remember ✔ Always pass a function reference to event handlers ✔ Use arrow functions when passing parameters ✔ React events are synthetic events (work consistently across browsers) ✔ Proper event handling improves UI behavior and performance ✨ Mastering event handling is a big step toward building interactive and scalable React applications. #ReactJS #JavaScript #FrontendDevelopment #WebDevelopment #LearningReact #CodingTips #ReactHooks #EventHandling

Day 18 – JavaScript Challenge Built a “Load More Images” feature using React, focusing on incremental data loading and smooth user experience. This project helped me understand how modern applications handle large datasets efficiently. Key learnings: *Implemented “Load More” functionality *Dynamic rendering of images *State management using React hooks *Improved performance by loading content gradually Each project is helping me bridge the gap between React concepts and real-world frontend development. #ReactJS #JavaScript #FrontendDevelopment #WebDevelopment #ReactHooks #UIFeatures #100DaysOfCode #DeveloperJourney
