React Conditional Rendering Patterns

Custom hooks in React - this is where the real power lies, dost! If you find yourself repeating the same logic in multiple components, extract it to a custom hook. It's not just about reusability - it's about: - Separation of concerns - Testability - Readability - Maintainability Common patterns: - useFetch for API calls - useLocalStorage for persistent state - useDebounce for search inputs - useWindowSize for responsive behavior Start with "use" prefix - it's a convention that helps React and tools identify hooks. And remember, hooks can call other hooks! That's the beauty of composition. What custom hooks have you created?

JavaScript Prototype Explained Simply (Must Know Concept) Why Prototype Matters? ✔ Code Reusability ✔ Memory Efficient ✔ Enables Inheritance ✔ Foundation of JavaScript Classes Array.prototype → Object.prototype → null Methods like: • push() • pop() • map() • filter() Come from Array.prototype const arr = [10, 20, 30]; console.log(arr.__proto__ ===Array.prototype); // true If you're learning JavaScript, mastering Prototype is a game changer 💪 #JavaScript #WebDevelopment #Frontend #Programming #Developers #CodingJourney

In JavaScript, the switch statement is a clean and organized way to handle multiple scenarios from a single expression — perfect when you’d otherwise end up chaining several if/else statements. - Improves readability when there are many possible cases - Use case for each condition and break to avoid “falling through” to the next case - Include default to guarantee a fallback behavior - Great for menus, status, action types, simple routing, and value mapping 💡 Practical tip: when cases start getting complex, consider using functions or mapping objects to keep the code even more scalable. #JavaScript #JS #Frontend #WebDevelopment #Programming #CleanCode #DevTips #Coding #SoftwareDevelopment #Tech

Every developer starts somewhere. HTML taught me structure. CSS taught me presentation. JavaScript taught me logic. React taught me scalability. TypeScript taught me reliability. Technology evolves — and so must we. You can’t build powerful applications without strong fundamentals. The real upgrade isn’t the framework… it’s the mindset. From writing simple static pages to building scalable full-stack applications — the journey continues. Always learning. Always building. 💻🔥 #WebDevelopment #FrontendDeveloper #ReactJS #TypeScript #MERNStack #Programming #TechGrowth #SACHIN BHASKAR

🧠 Ever wondered where a variable is accessible in your code? That’s called scope. JavaScript mainly has three types of scope 👇 🔹 Global Scope Variables declared outside any function or block Accessible everywhere 🔹 Function Scope Variables created inside a function Accessible only within that function 🔹 Block Scope Variables created inside { } (let and const only) 💡 This is why: ❌ var can cause bugs ✅ let & const are safer Understanding scope helps you: - Avoid variable conflicts - Write predictable code - Debug faster Scope isn’t advanced — it’s foundational JavaScript 🚀 #JavaScript #Scope #Frontend #WebDevelopment #LearnJS #Programming #LearningInPublic

🌟 CSS justify-content is one of the most useful properties in layouts. Especially when you are using a flex or grid container. It can be difficult to remember all the value options, though, and what they do. Hopefully, this video will help you remember as well as provide a demo of the outcomes. 😍If you like it, support me by reposting! ❤️Don’t forget write your opinions in the comments 👩🏻💻Follow Dorsa Asnavandi for more posts 🚀Start free learning with w3schools.com #htmlcss #css #csstips #csstricks #frontenddeveloper #frontenddevelopment #programming #reactjs #fullstackdeveloper

💡 A cleaner way to assign values conditionally in JavaScript (??=, ||=, &&=) Instead of writing verbose if statements for defaults and conditional updates, JavaScript conditional assignment operators let you express intent in one line #JavaScript #WebDev #Coding #Frontend #Programming #ES2021

Key prop in React lists - yeh ek chota sa thing hai but bahut important hai! I see developers using array index as key when they shouldn't. Index as key is fine ONLY if: - The list is static (never reordered, added, or removed) - Items don't have unique IDs - Performance isn't a concern But if your list can change, use a unique ID. React uses keys to identify which items changed, were added, or removed. Wrong keys = wrong updates = bugs! Also, don't use Math.random() as key. That's just wrong on so many levels. Each render will create new keys, causing unnecessary re-renders. Best practice: Always use stable, unique identifiers.

Unpopular opinion: "Performance" is a feature, not an afterthought. Most devs wait until the site feels "heavy" to start optimizing. By then, your bounce rate has already spiked. I wanted to make the technical side of speed easier to digest, so I built a checklist with the exact benchmarks you should be hitting in 2026 Whether you're a junior dev or a senior architect, this should be in your bookmarks. 🔖 Link: https://lnkd.in/eq_Np6JJ #WebDesign #Programming #TechTips #JavaScript

JavaScript Hoisting Explained.................. In JS, var declarations are hoisted to the top during the creation phase, initialized as undefined. So console.log(x) before assignment outputs undefined, then x = 5 assigns the value, and the second console.log(x) shows 5. #WebDev #JavaScript #Hoisting #Frontend #JSBasics #Coding #Programming #DeveloperTips #VarDeclaration #ExecutionContext
