Optimize React Native for Better Performance

Exploring #ArrowJS , a minimalist approach to modern frontend development ArrowJS is an experimental #JavaScript library for building reactive user interfaces using native JS, without the overhead of traditional frameworks. It challenges the idea that complex tooling is required to build powerful UIs. Key highlights: • ⚡ Ultra-lightweight (~3KB) with zero dependencies • 🧩 No build step, no virtual DOM, no custom templating language • 🔄 Reactive by choice — not by default • 🧠 Leverages modern JavaScript features like template literals, modules, and proxies • 🚀 Fast and simple, with a focus on developer ergonomics The core idea? JavaScript itself has evolved enough that we don’t always need heavy frameworks to create dynamic, performant applications. ArrowJS embraces that philosophy with a “less is more” approach. Worth checking out if you’re interested in lightweight alternatives to React/Vue or exploring new patterns in frontend architecture. #JavaScript #WebDevelopment #Frontend #SoftwareEngineering #Programming #WebDev #DeveloperTools #React #Vue

🚀 React Hooks — All in One (Simple Explanation) Hooks let you use state & lifecycle features in functional components in React. 🔹 useState Manages local state ➡ State change = UI update const [count, setCount] = useState(0); 🔹 useEffect Handles side effects (API calls, subscriptions, timers) useEffect(() => {}, []); 🔹 useContext Share data globally (No prop drilling) 🔹 useRef Access DOM & store values (No re-render) 🔹 useMemo Optimize heavy calculations (Recompute only when needed) 🔹 useCallback Optimize functions (Avoid unnecessary re-renders) 🔹 useReducer Handle complex state logic (Like Redux pattern) 🔹 useLayoutEffect Runs before browser paint (Used for layout work) 🔹 Custom Hooks Reuse logic across components (Clean & maintainable code) 💡 One-Line Summary Hooks make React code simpler, cleaner, and more powerful. 👍 Like | 💬 Comment | 🔁 Share #React #JavaScript #WebDevelopment #Frontend #Coding #100DaysOfCode

🚀 What is React.js? (Explained Simply) Modern web applications need fast, interactive, and scalable user interfaces. That’s where React.js comes in. React is a JavaScript library used to build dynamic and component-based user interfaces. Instead of building a full page again and again, React allows developers to create reusable components. Think of it like building a website with LEGO blocks. Each block can represent a part of the UI like: • Navbar • Button • Product card • Dashboard widget React also uses Virtual DOM, which updates only the changed part of the page instead of reloading everything. Result: ✔ Faster applications ✔ Better user experience ✔ Reusable components ✔ Scalable architecture That’s why many modern applications rely on React. Still learning. Still building. 🚀 — Anuj Pathak #reactjs #javascript #webdevelopment #frontenddevelopment #softwareengineering #developersoflinkedin #programming #techlearning #learninginpublic #webdeveloper #codinglife #softwaredeveloper #buildinpublic

React has a really elegant pattern that many developers don’t take advantage of. Instead of controlling components with dozens of props, React allows you to compose components using smaller building blocks. This pattern is often called compound components. The idea is simple: instead of configuring a component through many props, the parent component exposes smaller components that you can combine however you want. It actually took me some time working with React to realize this pattern existed, so this post is mostly for those who are earlier in their journey. If you didn’t know about this concept, you’ve probably already seen it in component libraries like Material UI, Radix UI, etc... It’s a simple idea, but it makes components much more flexible and easier to scale. Here’s a small example. #React #JavaScript #Frontend #WebDevelopment #SoftwareEngineering

⚛️ Understanding the Inner Workings of React React looks simple on the surface — components, props, and state. But behind the scenes, React has a powerful system that makes UI updates fast and efficient. Here are a few key concepts that power React internally: 🔹 Virtual DOM Instead of updating the real DOM directly (which is slow), React creates a Virtual DOM, a lightweight copy of the UI. React compares the new Virtual DOM with the previous one and updates only the parts that changed. 🔹 Reconciliation React uses a smart diffing algorithm to figure out what changed between renders. This process is called reconciliation, and it helps React update the UI efficiently. 🔹 Fiber Architecture React introduced Fiber to improve rendering performance. It allows React to break rendering work into smaller chunks, making applications smoother and more responsive. 🔹 Component-Based Architecture React applications are built with reusable components, making code easier to maintain and scale. Understanding how React works internally helps developers write better optimized and scalable applications. Learning React is not just about using hooks and components — it’s about understanding the system behind the framework. #ReactJS #FrontendDevelopment #WebDevelopment #JavaScript #ReactDeveloper

#Day59 of #100DaysOfCode Today I explored some important React and JavaScript concepts that help in building interactive web applications. 🔹 Handling Click Events – Learned how React responds to user clicks using event handlers like onClick. 🔹 Handling Non-Click Events – Explored events like keyboard input, form changes, and mouse movements. 🔹 Event Object – Understood how React provides event information (like target element, value, etc.) through the event object. 🔹 State in React – Learned how state helps store dynamic data and update the UI automatically. 🔹 Hooks – Got introduced to React Hooks which allow functional components to use features like state and lifecycle behavior. 🔹 useState() Hook – Practiced managing component state using useState. 🔹 Activity: Create Like Button – Built a simple Like Button to practice state updates and user interaction. 🔹 Closures in JavaScript – Understood how functions can access variables from their outer scope even after execution. 🔹 Re-render in React – Learned how React re-renders components when state or props change. 🔹 Callback in setState Function – Explored how callback functions help update state based on the previous state. 🔹 More About State – Deepened understanding of how state works internally in React. #React #JavaScript #MERN #WebDevelopment #100DaysOfCode #Day59complete✅👍🏻

How I Keep My React Components Clean and Maintainable Over time, I’ve realized that clean code isn’t just about making things work it’s about making them easy to understand, reuse, and scale. Here’s what I focus on 1. Small Components Break UI into smaller pieces instead of one big component. Smaller components are easier to read, test, and debug. 2. Reusable Logic Avoid repeating the same logic everywhere. If something is used multiple times, extract it. 3. Custom Hooks Move logic into custom hooks like useFetch, useAuth, etc. This keeps components clean and focused only on UI. 4. Separation of Concerns Keep UI, logic, and data handling separate. Don’t mix everything in one file. Clean components = Better performance + Easier maintenance + Faster development What’s your approach to writing clean React code? #React #FrontendDevelopment #JavaScript #WebDevelopment #CleanCode #CodingTips

Why do simple React UIs sometimes become hard to maintain? In my experience, it’s usually not because of the components — it’s because of unclear UI states when dealing with APIs. Recently while working on a feature, the UI logic started getting messy even though the layout was simple. The real issue was that the component wasn’t explicitly handling different API states. We restructured the flow around four clear states: • Loading – when the API request is in progress • Error – when the request fails • Empty – when the API returns no results • Success – when valid data is available Once these states were handled clearly, the component logic became much simpler and the UI behavior became far more predictable. Small pattern, but it makes a big difference in API-driven React applications. Curious how others structure UI states in their React projects. #reactjs #frontendengineering #javascript #webdevelopment #uidevelopment
