⚛️ Props in React — Explained Simply Props are how components communicate in React. They allow you to: • Pass data from parent to child • Build reusable components • Keep your UI dynamic and clean 👉 Important: Props are read-only and should not be modified. Example: 📌 Think of props like function arguments — they help you customize components. Are you using props effectively in your projects? #ReactJS #FrontendDevelopment #JavaScript #WebDevelopment #Coding #ReactTips

Building My Own Reusable Star Rating Component in React As part of my journey learning React, I decided to stop relying on external npm packages for simple UI features (For security and Reliability reasons) and instead build them from scratch. One of the components I built recently is a fully reusable Star Rating component Features I implemented: - Configurable number of stars (max) - Controlled and uncontrolled rating support - Click interaction to set rating - Custom colors support (border, fill, shadow) - Reset / clear rating option - Callback function triggered when the user selects a rating, passing the updated rating value as an argument , this is helpfull for external handling (e.g: state sync with parent components) - Fully reusable design #React #JavaScript #FrontendDevelopment #WebDevelopment #LearningInPublic #Programming #UI #CleanCode

🚀 React Series – Day 7 Rendering Based on Conditions (Making UI Smarter) Not every part of the UI should always be visible. Sometimes, what users see depends on certain conditions. React allows this through conditional rendering. Common approaches include: • Using if/else statements • Ternary operators • Logical && For example, showing a dashboard only when a user is logged in. 👉 This makes applications more dynamic and improves user experience by displaying only relevant content. #reactjs #javascript #frontenddeveloper #webdevelopment #codinginterview #learnreact #30daysofcode #programming #reactinterview #react #coding
