"Thales Domingues Tip: Using useEffectEvent hook in React"

Finally, React has provided a way to access the latest props and states in effects (useEffect/useLayoutEffect) without causing re-renders. The useEffectEvent hook will help achieve this. The hook helps extract non-reactive logic from useEffect webhooks. Non-reactive logic refers to when we don't want to perform any action. The useEffectEvent hook wraps a callback function and returns an Effect Event function, and whenever it gets called, the function has access to the latest props and state. So, it won't trigger a re-render, unlike in the case of dependency arrays. But it's not the replacement of the dependency array, as that is usually required to trigger effects. You should try it in your workflow as per the use cases. #react #javascript #frontend #hooks

🤯 Stop the Flash! Learn the difference between useLayoutEffect and useEffect in React! useLayoutEffect is your secret weapon for synchronous DOM updates and measurements BEFORE the browser paints the screen. Perfect for preventing visual glitches (like flash of unstyled content) when you need to adjust layout based on rendered elements. If you don't need to read or manipulate the DOM synchronously, stick to useEffect for better performance! Which hook do you use more?

Two hooks are often ignored because they feel niche, yet they unlock sharp control in specific scenarios 🪝 useLayoutEffect runs after DOM mutations but before the browser paints. It is ideal for measuring layout, syncing scroll positions, and avoiding visual flicker during first paint. useImperativeHandle lets a parent call controlled methods on a child wrapped with forwardRef. It is perfect for exposing focus, reset, or validate methods on complex inputs. Use them sparingly and document the reason. Prefer useEffect for most cases and a declarative approach the rest of the time. Reach for these only when standard patterns fall short. A small example speaks loudly. Build a custom TextInput that exposes focus via useImperativeHandle and prevents flicker on mount with useLayoutEffect. Show the user benefit clearly. Mastery is knowing the right tool and the minimal surface area to solve it. These hooks provide both when used with care. ✨ #ReactJS #Hooks #WebDev #FrontendDevelopment #JavaScript

🚀 Mastering the JavaScript Intersection Observer API! One of the most powerful yet underutilized APIs in modern web development is the Intersection Observer. Here's why it's a game-changer: ✨ Key Benefits: • Lazy load images efficiently without blocking the main thread • Trigger animations when elements enter the viewport • Implement infinite scroll with minimal performance impact • Track element visibility with extreme precision 💡 Real-World Use Cases: 📸 E-commerce sites loading product images on demand 🎬 Portfolio sites triggering animations as you scroll 📚 News feeds implementing endless scrolling ⚡ Performance optimization by reducing initial load time 🔧 The best part? No more scroll event listeners with countless redraws. Intersection Observer handles everything efficiently! #WebDevelopment #JavaScript #Frontend #Performance #Coding

I used to mix up when to use v-if and when to use v-show 😅 Then this simple understanding helped: v-if → Adds/Removes the element from the DOM v-show → Just hides/show with CSS So now my rule: ✅ Use v-if when something should appear conditionally and not often ✅ Use v-show when you toggle visibility frequently (like dropdowns, tabs, filters) This small clarity made my UI more efficient and predictable. Sometimes the simplest concept saves the most time 😄 #VueJS #Frontend #WebDevelopment #JavaScript #LearningByDoing

💥Virtual DOM in React: The Secret Behind Its Speed 🔹The Virtual DOM is a lightweight copy of the real DOM that React uses to handle UI updates efficiently. 🔹 When a component’s state changes, React updates the Virtual DOM first instead of the real DOM. 🔹It then compares the new Virtual DOM with the old one using a process called diffing to find changes. 🔹Only the changed parts are updated in the real DOM, making the process faster and more efficient. 🔹This approach reduces unnecessary rendering and improves the performance of React applications. #StemUp #ReactJS #VirtualDOM #FrontendDevelopment #JavaScript

Here's what you're missing with the new architecture. ⚡ 2x faster startup 🎯 Smooth 60 FPS animations 🚀 Direct native calls (no more JSON overhead) I put together a simple comparison guide showing: - Old vs new side by side - Real performance differences - Migration steps Easy tables.

I guess one of the first software programs I interacted with as a kid was Winamp ⚡, intrigued by bar sounds and how they react to different sounds. It's impressive how easy it is to recreate this behavior in JavaScript. On this website (https://lnkd.in/dqSEChiN), I show how we can display sound bars based on microphone input. And of course, here is the codebase: https://lnkd.in/dc2emKGp #JS #javascript #frontend #webdevelopment #webdev

React's New <Activity> Component 🔥: Say Goodbye to Lost State! Are you still using the && operator or display: none to hide components? That's the old way! The <Activity> component is a massive step up from traditional Conditional Rendering. When you set it to mode="hidden", here's what happens: 💾 It preserves the component's State and DOM structure (State Preserved). 🧹 It cleans up Side Effects like useEffect, ensuring no background performance drain (Effects Cleaned Up). 🚀 It's perfect for Fast Navigation and Instant State Restoration in complex UIs like Tabbed Interfaces, Carousels, or Wizard Forms. Check out the comparison image to see the difference between the old method (where state is lost) and the new Activity component! What are your thoughts on this new concept? Are you planning to use the <Activity> component in your next project?

🎨 Frontend Styling Tip of the Day! Ever found yourself writing messy conditional classnames like this? 😅 <div className={isActive ? 'btn active' : 'btn'}>Click Me</div> Here’s a cleaner, smarter way using clsx 👇 import clsx from 'clsx'; <div className={clsx('btn', { active: isActive })}>Click Me</div> Why this rocks 🚀 ✅ Makes your code shorter and more readable ✅ Keeps your logic and styling cleanly separated ✅ Easily scales as conditions grow A small utility 💫 that saves you from a big mess when styling React components. #ReactJS #WebDev #FrontendTips #CleanCode #CSS
