🚀 “When you know the answer… but say it wrong under pressure 😅” Today’s React.js interview was a rollercoaster. 💻 Everything was going smooth — ✔ JavaScript concepts (event loop, closures) ✔ React topics (code splitting, lazy loading) ✔ Problem-solving discussions Then came the live coding + screen share round 👇 I had to build a small React app and explain what happens on state update — like mount, re-render, unmount. 👉 And that’s where things got funny (and real). I knew the concepts… but under pressure, I kept calling re-render as unmount 🤦♂️ For a few moments, even the interviewer smiled… and then I realized — I was just mixing terms, not lacking knowledge. 💡 That moment taught me something important: Interviews don’t just test what you know… they test how clearly you can express it under pressure. 👉 I corrected myself later, but yeah — that slip stayed with me. Still, I’m taking this as a win: ✔ I didn’t panic ✔ I stayed honest ✔ I learned exactly where I need improvement Now I’ll focus more on: ✔ Clear communication of concepts ✔ Practicing under real interview pressure Because growth comes from these exact moments. 🚀 --- Reference (for preparation): - Webpack Bundle Optimization - Handling pressure in live coding rounds --- #ReactJS #FrontendDeveloper #JavaScript #InterviewExperience #ReactDeveloper #CodingInterview #DevelopersLife #LearningJourney #Frontend #WebDevelopment #JobSearch #InterviewPrep #SoftwareEngineer #KeepLearning #CodeDaily #ReactInterview #JS #WebDev #CareerGrowth 😅

🚀 Day 9/90 — Becoming a Job-Ready Frontend Engineer Today I went deeper into Advanced Array Methods in JavaScript — the kind of concepts that are used daily in React applications and frequently asked in interviews. Focused on: 🔹 sort() — and why it can be dangerous if you don’t use a compare function 🔹 find() — returning the first matching item 🔹 some() — checking if at least one condition passes 🔹 every() — verifying if all elements satisfy a condition One important realization: By default, sort() converts elements to strings before comparing — which can lead to unexpected results. Example: [10, 2, 5].sort() → ❌ Incorrect order Correct approach: array.sort((a, b) => a - b) Another key learning: Understanding the difference between: • find() → returns a single item • filter() → returns a new array • some() → returns boolean (stops early) • every() → returns boolean (stops early) These methods are essential for: ✔ Rendering filtered lists in React ✔ Handling API data ✔ Validating form conditions ✔ Writing clean, functional JavaScript The more I practice arrays, the more I realize frontend engineering is about thinking functionally and avoiding unnecessary mutations.

💡 Interview Insight: JavaScript Event Loop & Microtasks One of the interesting questions I was recently asked in an interview: 👉 “How would you move a task into the microtask queue in JavaScript?” This question dives deep into how the event loop works — something every frontend developer should understand beyond just theory. Here’s the essence: Microtasks have higher priority than macrotasks. They are executed right after the current call stack, before any rendering or next event loop tick. Common ways to push tasks into the microtask queue: Promise.resolve().then(...) queueMicrotask(...) MutationObserver (less common but interesting) ✨ Example: console.log("Start"); Promise.resolve().then(() => { console.log("Microtask"); }); console.log("End"); // Output: // Start // End // Microtask 🔍 Why it matters: Understanding this helps in: Writing predictable async code Debugging tricky timing issues Optimizing performance in real-world apps E-mail: panditdeshant@gmail.com #JavaScript #FrontendDevelopment #WebDevelopment #EventLoop #AsyncJavaScript #InterviewQuestions #Learning #OpenToWork

🚀 Day 8 – Crack Interviews Series 🔹 Topic: What is Prototype in JavaScript? Every JavaScript object has a hidden property called prototype that allows it to inherit properties and methods from other objects. 👉 This is how inheritance works in JavaScript. 💡 Real Example: function Person(name) { this.name = name; } Person.prototype.greet = function () { console.log("Hello " + this.name); }; const user = new Person("Priyanshu"); user.greet(); // Hello Priyanshu 👉 "greet()" is not inside the object, but still accessible via prototype. 🎯 Interview Question: What is the prototype chain? 👉 Answer: It’s a chain of objects where JavaScript looks for properties if not found in the current object. 💼 Pro Tip: Modern JavaScript uses "class", but under the hood it still works with prototypes. 👇 Have you explored prototype vs class deeply? 👉 Follow the Hireful Jobs channel on WhatsApp: https://lnkd.in/ghaHMBUB Telegram: https://t.me/hireful #javascript #webdevelopment #frontend #nodejs #interviewprep #coding #developers

Frontend interviews aren’t really about React… Here’s a round-wise breakdown with some of the most asked questions 👇 🔹 JavaScript (Most Important Round) This is where most candidates struggle. 1.

Promise chaining vs async/await 🔹 Round 2: React Deep Dive 1. Why do components re-render? 2. useMemo vs useCallback vs React.memo 3. How does useEffect lifecycle work? 4. How do you prevent unnecessary renders? 5. Real-world state management approach 🔹 Round 3: Machine Coding 1. Build a debounced search / autocomplete 2. Handle API calls with proper states 3. Focus on clean architecture & reusability 4. Edge cases + performance considerations 🔹 Round 4: Frontend System Design 1. Design a scalable UI (dashboard/feed) 2. Folder structure & code organization 3. API handling and caching 4. Performance optimization techniques 🔹 Round 5: Hiring Manager Round 1. Deep dive into your project 2. Why did you choose certain approaches 3. Challenges and trade-offs 4. Ownership and decision making 💡 Biggest takeaway: Frameworks change, but strong fundamentals stay.

🚀 JavaScript Closures – Explained Simply (Interview Ready!) If you’re preparing for frontend interviews, closures is one topic you must master 💯 👉 What is Closure? A closure is when a function remembers variables from its outer scope even after the outer function has finished executing. 💡 In simple terms: Function + its lexical scope = Closure --- 🔍 Example: function outer() { let count = 0; return function inner() { count++; console.log(count); }; } const fn = outer(); fn(); // 1 fn(); // 2 fn(); // 3 👉 Even after "outer()" is executed, "inner()" still remembers "count" That’s the power of closures! --- 🔥 Real-world Uses: ✔ Data hiding (private variables) ✔ Event handlers ✔ setTimeout / async operations ✔ React hooks (useState, useEffect) --- ⚠️ Common Mistake: Closure ≠ just “function inside function” It’s about remembering the outer scope --- 🎯 One-liner for interviews: “Closure is when a function retains access to its lexical scope even after the parent function has executed.” --- 💬 Mastering closures = stronger JavaScript fundamentals + better problem-solving in React #JavaScript #Frontend #ReactJS #WebDevelopment #InterviewPrep #Closures #Coding
