Stop Using Any in TypeScript, It's a Red Flag

🔥 JavaScript Devs — Async/Await Doesn’t Always Save You Hey devs 👋 We all love async/await… Clean, readable, simple. But here’s the problem 👇 👉 It’s still easy to make mistakes. 💥 Example: await Promise.all([ fetchA(), fetchB(), fetchC() ]) 👉 If ONE fails → everything fails. 💡 What I do now: ✔ Handle errors individually ✔ Use Promise.allSettled when needed ✔ Don’t assume success ⚡ Insight: “Cleaner syntax doesn’t mean safer code.” 👉 Senior mindset: Always think about failure cases. How do you handle async failures? #javascript #asyncawait #promises #errorhandling #webdevelopment #programmingtips #frontenddeveloper #backenddeveloper #softwareengineering #js

Most important question that was asked in React Developer interview Sharing the questions here in case it helps someone preparing for similar roles. Some of the questions they asked: 1. What is React and why is it efficient? 2. How does React work internally? 3. What is the most challenging task you handled in your project? 4. Is JavaScript tightly coupled or loosely coupled? 5. Why do we use TypeScript? 6. How does "extends" work in TypeScript and what is the difference between type and interface? 7. How does Redux work, from installation to usage in a project? 8. Have you used Redux Toolkit (RTK) or TanStack Query? 9. What is the difference between bind and apply in JavaScript? 10. What has been your experience with useCallback and useMemo in real projects? 11. What is the role of the dependency array in useEffect? Overall, the round was focused on practical understanding of React, TypeScript and JavaScript rather than just theory. 👨💻 Follow for daily React, and JavaScript #React #JavaScript #TypeScript #Redux #Frontend #InterviewExperience #capgemini

𝗝𝗮𝘃𝗮𝗦𝗰𝗿𝗶𝗽𝘁 𝗘𝘃𝗲𝗻𝘁𝗟𝗼𝗼𝗽 𝗘𝘅𝗽𝗹𝗮𝗶𝗻𝗲𝗱 (𝗔 𝗠𝘂𝘀𝘁‐𝗞𝗻𝗼𝘄 𝗖𝗼𝗻𝗰𝗲𝗽𝘁) Understanding the JavaScript Event Loop is a game changer for writing efficient and predictable asynchronous code. Many developers use setTimeout and Promises every day — but far fewer truly understand how JavaScript executes async tasks behind the scenes. Let’s break it down 👇 𝗛𝗼𝘄 𝘁𝗵𝗲 𝗘𝘃𝗲𝗻𝘁 𝗟𝗼𝗼𝗽 𝗪𝗼𝗿𝗸𝘀 • JavaScript runs on a single thread • Synchronous code executes first via the Call Stack • Then Microtasks run (like Promises) • Next, one Macrotask executes (timers, events) • This cycle continues repeatedly 𝗘𝘅𝗲𝗰𝘂𝘁𝗶𝗼𝗻 𝗣𝗿𝗶𝗼𝗿𝗶𝘁𝘆 ➡️ Synchronous ➡️ Microtasks ➡️ Macrotasks 𝗪𝗵𝘆 𝘁𝗵𝗶𝘀 𝗰𝗼𝗻𝗰𝗲𝗽𝘁 𝗺𝗮𝘁𝘁𝗲𝗿𝘀 ✅ Debug async issues with confidence ✅ Avoid unexpected execution order ✅ Build more predictable React applications ✅ Frequently tested in frontend interviews #JavaScript #EventLoop #FrontendDevelopment #ReactJS #WebDevelopment #InterviewPrep #AsyncJavaScript #SoftwareEngineering

🚀 Day 2 of 30 Days of TypeScript JavaScript vs TypeScript — Real-World Comparison (Not Just Theory) We’ve all heard: “TypeScript is better than JavaScript.” But the real question is… how does it actually help in real projects? 🤔 From my experience 👇 🔹 JavaScript gives you flexibility …but also surprises you in production 😬 🔹 TypeScript adds structure …and catches issues before they become bugs 🚀 👉 The biggest difference? It’s not syntax. It’s confidence while building at scale. Fewer runtime errors Safer refactoring Better team collaboration Cleaner, self-documented code 💡 Simple rule I follow: Small scripts → JavaScript ✅ Real-world apps → TypeScript 🔥 🔥 Final Thought TypeScript doesn’t slow you down… It prevents you from slowing down later. 💬 Have you faced a bug in JavaScript that TypeScript could’ve prevented?

Great developers don’t try to remember everything. They build systems that remember for them. A cheat sheet isn’t a shortcut— it’s a smart way to move faster.

Most developers use JavaScript. Only a few actually understand it deeply. That’s the difference between getting rejected and getting selected in frontend interviews. If you want to stand out, these JavaScript concepts are non-negotiable 👇 🧠 Execution Context, Call Stack & Hoisting 🔒 Closures, Scope & Lexical Environment ⚡ Async JavaScript (Promises, Async/Await, Fetch) 🔁 Event Loop, Microtasks & Callback Queue 🧩 Objects, Prototypes & this keyword 🛠️ Call, Apply, Bind 📦 Arrays (map, filter, reduce) 🚀 ES6+ (Destructuring, Spread, Modules) 🌐 DOM Manipulation & Event Delegation 🔥 Debouncing & Throttling 🧪 Error Handling & Memory Management You need strong JavaScript fundamentals. Master this → You’re already ahead of most developers. #javascript #frontenddeveloper #webdevelopment #reactjs #coding #developers #100DaysOfCode

Most developers avoid TypeScript. Here's why that's a mistake. 🧵 I used to think TypeScript was just "extra work." Then I spent 3 hours debugging a production bug... ...that TypeScript would have caught in 3 seconds. 😅 The real difference? JavaScript: ❌ No type safety ❌ Runtime errors ❌ Hard to debug TypeScript: ✅ Full type safety ✅ Catch errors early ✅ Clean & scalable If you're building anything serious in 2026 — TypeScript isn't optional anymore. It's just professionalism. Are you still writing plain JavaScript?
