Ingenious React Jobs – Chennai’s Post

💡 **Daily React/JavaScript Interview Tip** The event loop isn’t just theory—it explains **why your code runs in a certain order**. 👉 Weak answer: “The event loop handles async operations.” ✅ Stronger answer: “JavaScript is single-threaded, so it uses the event loop to manage async tasks. Synchronous code runs first, then callbacks from the task queue (like `setTimeout`) and microtask queue (like Promises) are processed. Microtasks always run before the next task, which is why Promise callbacks execute before `setTimeout`.” 🧠 Example: ```js console.log('A'); setTimeout(() => console.log('B'), 0); Promise.resolve().then(() => console.log('C')); console.log('D'); ``` 👉 Output: A D C B 📌 Tip: If you can clearly explain **call stack, task queue, and microtask queue with an example**, you’ll stand out instantly. #JavaScript #EventLoop #WebDevelopment #AsyncJavaScript #TechInterviews

🚀 Higher-Order Functions (JavaScript) Higher-order functions are functions that either take one or more functions as arguments or return a function as their result. They are a fundamental concept in functional programming, enabling powerful abstractions and code reuse. Examples include `map`, `filter`, and `reduce`, which operate on arrays by applying a function to each element or combining elements into a single value.

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
