This ES6+ feature made asynchronous JavaScript feel more… human 🙂 Yes this is async/await! Think of async/await like placing an order at a café. You order your coffee. Instead of standing there blocking the entire world, you sit down and wait. When the coffee is ready → you continue. That’s basically what await does. #javscript #coding #react

👀 This is literally JavaScript vs TypeScript. BEFORE → JavaScript Works? Yes. Understands it? Nobody. Touch one thing and pray 🙏 AFTER → TypeScript Same code. Same logic. But now every "wire" has a type, a label, and a purpose. Your team can actually read it. Your IDE helps you. Bugs get caught before they hit production. I just migrated my project from JS to TS and this image is the most honest thing I've ever seen 😂 The wires didn't change — the structure did. That's TypeScript. #TypeScript #JavaScript #WebDev #CleanCode #100DaysOfCode #Frontend #Programming #Brototype

Writing a code is one thing and writing a well-optimized and refactored code is another thing. A well optimized code differs you from other developers who are just writing code without knowing how it impacts performance. Here is an example of a refactored code: Modern Js uses Ternary operators and modern Es6 syntax instead of If/else blocks. #javaScript, #coding, #code,#performance,#refactored, #js,#programming,

This journey completely changed how I think about JavaScript development. TypeScript isn’t just “JavaScript with types.” It’s a type system + compiler + developer tooling enhancer that makes large-scale applications safer, maintainable, and easier to refactor. Catching errors at compile time instead of production? Game changer

⚡ What if your Node.js script could behave like a real terminal command? Not like this: node script.js But like this: mytool greet Shaheryar Just like git, npm, or docker. The strange part? It only takes one tiny line of code and a small npm trick to turn a normal script into a global CLI command. In my latest article I show how this works — and why many popular developer tools secretly use the same mechanism. 👉 Full article: https://lnkd.in/dGjFAJYc If you could build one custom CLI command for your workflow, what would it be? 👀 #NodeJS #JavaScript #DevTools #CLI #Programming #SoftwareEngineering #Developers

💡 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

🚀 𝗥𝗲𝗮𝗰𝘁 𝟭𝟵 & 𝗥𝗲𝗮𝗰𝘁 𝗖𝗼𝗺𝗽𝗶𝗹𝗲𝗿 𝗮𝗿𝗲 𝗵𝗲𝗿𝗲! React is evolving to make performance optimization smarter and more automatic. With the new React Compiler, developers can reduce unnecessary re-renders without relying heavily on useMemo and useCallback. ⚛️ 𝗖𝗹𝗲𝗮𝗻𝗲𝗿 𝗰𝗼𝗱𝗲 ⚡ 𝗕𝗲𝘁𝘁𝗲𝗿 𝗽𝗲𝗿𝗳𝗼𝗿𝗺𝗮𝗻𝗰𝗲 🧠 𝗦𝗺𝗮𝗿𝘁𝗲𝗿 𝗿𝗲𝗻𝗱𝗲𝗿𝗶𝗻𝗴 This update helps teams focus more on building features and less on micro-optimizations. If you're working with modern React, now is the perfect time to explore these improvements. #React #React19 #JavaScript #Frontend #WebDevelopment #Programming #TechUpdate

🚀 30 Days — 30 Coding Mistakes Beginners Make Day 8/30 My backend server CPU suddenly went high 🔥 The reason? A simple `useEffect`. I wrote an API call inside `useEffect`… and forgot the dependency array. By default, `useEffect` runs after EVERY render. Inside it I was updating state → which caused another render → which called the API again. Infinite request loop. Fix 👇 useEffect(() => { fetchUsers(); }, []) Empty dependency array = run only once on mount. Small brackets. Huge difference.
