React Patterns for Stable Apps

🚀 Day 13 of Consistent Learning – React Journey Continuing to strengthen understanding of React hooks. 🔹 What I covered: - Initializing state with a callback - React Hooks and their rules - useRef hook - Selecting DOM elements using useRef 🔹 Key takeaway: Using a callback for state initialization can improve performance in certain cases. The rules of hooks ensure predictable behavior, and useRef is powerful for accessing DOM elements without causing re-renders. 🔹 Next step: Continue learning new React concepts step by step while strengthening these fundamentals. Diving deeper into hooks, one step at a time. #React #JavaScript #WebDevelopment #Frontend #LearningInPublic

🔗 Understanding Props in React As I continue learning React, today I explored Props — a key concept for building reusable components 💡 What are Props? Props (short for properties) are used to pass data from one component to another 📌 What I learned: • Props are read-only • They help make components reusable • Data flows from parent → child 🔧 Example: I passed search data from my main component to a child component to make it dynamic 🚀 Why it matters: Props help break down UI into smaller, manageable, and reusable pieces Understanding props made my code more structured and cleaner 💡 Learning step by step and building consistency 🚀 #ReactJS #FrontendDevelopment #Props #JavaScript #WebDevelopment #LearningInPublic

🚀 Day 11 of Consistent Learning – React Journey Continuing to explore deeper and more practical concepts. 🔹 What I covered: - How events work in React - Libraries vs frameworks - useEffect hook - Using async functions for data fetching from APIs 🔹 Key takeaway: Handling side effects with useEffect and fetching data asynchronously are essential for building real-world applications. Also, understanding the difference between libraries and frameworks gives better clarity on how React fits into the ecosystem. 🔹 Next step: Continue learning new React concepts step by step while strengthening these fundamentals. Moving closer to real-world applications. #React #JavaScript #WebDevelopment #Frontend #LearningInPublic

When should you use useCallback in React? ⚛️ While learning about performance optimization, I realized functions can also cause unnecessary re-renders. ⸻ 🔹 useCallback It memoizes a function so it doesn’t get recreated on every render. ⸻ 💡 Why it matters: Every render creates a new function reference. This can trigger re-renders in child components. ⸻ 🧠 Simple understanding: Same dependencies → same function Changed dependencies → new function ⸻ ⚠️ Important: Don’t use it everywhere. Use it only when it actually improves performance. ⸻ Small optimization, better performance ⚡ #ReactJS #FrontendDevelopment #JavaScript #ReactHooks #Performance #LearningInPublic

Day 5 of Learning React JS 🚀 Today was all about going deeper into how React actually works behind the scenes. I focused on understanding state and props more clearly—and things are finally starting to click! Here’s what I explored today: 🔹 How state controls dynamic data inside components 🔹 Passing data using props and making components reusable 🔹 The importance of keeping components clean and modular 🔹 Practiced building a small interactive UI (and fixed a lot of bugs 😅) One key realization: React is less about memorizing syntax and more about thinking in components. It’s challenging at times, but also super rewarding when things start working the way you expect. Slowly building confidence step by step Looking forward to diving into hooks next! #ReactJS #WebDevelopment #LearningJourney #JavaScript #FrontendDevelopment #100DaysOfCode

🚀 Day 9 of Consistent Learning – React Journey Diving deeper into how React works behind the scenes. 🔹 What I covered: - How React works under the hood - Virtual DOM - React elements - Component instances 🔹 Key takeaway: Understanding the internal working of React makes everything clearer. The Virtual DOM and how React manages elements and instances explain why React is efficient and predictable. 🔹 Next step: Continue learning new React concepts step by step while strengthening these fundamentals. Learning beyond the surface level. #React #JavaScript #WebDevelopment #Frontend #LearningInPublic

🚀 Day 2 of Consistent Learning – React Journey Building momentum after getting back on track. 🔹 What I covered: - State management in React - Local vs Global state - Lifting state up - Derived state 🔹 Key takeaway: Understanding where state should live is crucial. Lifting state up helps keep data consistent across components, while derived state avoids unnecessary duplication and keeps logic clean. 🔹 Next step: Continue learning new React concepts step by step while strengthening these fundamentals. Staying consistent, one step at a time. #React #JavaScript #WebDevelopment #Frontend #LearningInPublic

🚀 Day 10 of Consistent Learning – React Journey (Late Update) Yesterday’s learning—posting this morning due to no internet access last night. 🔹 What I covered: - Diffing algorithm in React - Key prop and its importance - State update batching 🔹 Key takeaway: Small details like the key prop and how React batches state updates have a big impact on performance and UI behavior. Understanding diffing helps in writing more efficient and predictable components. 🔹 Next step: - How events work in React - Libraries vs frameworks Consistency continues, even with small obstacles. #React #JavaScript #WebDevelopment #Frontend #LearningInPublic

🚀 Day 14 of Consistent Learning – React Journey Stepping into more advanced and practical patterns. 🔹 What I covered: - Custom Hooks in React - Built "useLocalStorage" hook - Built "useKey" hook - Started a mini challenge 🔹 Key takeaway: Custom hooks make logic reusable and keep components clean. Creating my own hooks helped me understand how to abstract and organize functionality better. 🔹 Next step: Continue learning new React concepts step by step while strengthening these fundamentals. Building smarter abstractions, one hook at a time. #React #JavaScript #WebDevelopment #Frontend #LearningInPublic

🚀 Day 8 of Consistent Learning – React Journey (Late Update) Missed posting last night, but staying accountable and sharing today. 🔹 What I covered: - PropTypes for type checking in React - Started a mini project: Text Expander 🔹 Key takeaway: Using PropTypes adds a layer of reliability to components by catching bugs early. Starting small projects like Text Expander helps in applying concepts immediately and reinforces learning. 🔹 Next step: Continue learning new React concepts step by step while strengthening these fundamentals. Consistency continues, even if the timing isn’t perfect. #React #JavaScript #WebDevelopment #Frontend #LearningInPublic
