Today I learned about Lists & Keys in React. Lists allow us to render multiple items dynamically using methods like map(). For example: We can display a list of users, products, or tasks easily. Keys are used to uniquely identify each item in a list. This helps React efficiently update only the changed elements instead of re-rendering everything. Using unique keys improves performance and avoids bugs. Up Next: Forms in React 👀 React Series – Day 8 🚀 #ReactJS #LearningInPublic #WebDevelopment #FrontendDeveloper #JavaScript #100DaysOfCode

Many beginners think querySelector() in JavaScript and useRef() in React do the same thing. But React uses a Virtual DOM, so direct DOM manipulation can break React’s flow. That’s why useRef() gives controlled access to the DOM while keeping React’s architecture intact. Learning something new every day in my React journey. 🚀 #ReactJS #JavaScript #WebDevelopment #FullStackDevelopment

One of the Best YouTube Videos on JavaScript Event Loop 🧑💻 The JavaScript Event Loop is one of the most important concepts to understand if you want to know how JavaScript handles asynchronous operations. I recently watched this video by Lydia Hallie and honestly, it’s one of the best explanations of the Event Loop on YouTube. She explains concepts like Call Stack, Web APIs, Task Queue and Microtask Queue in a very clear and visual way. If you want to understand how the Event Loop works, just watch this video once.

🚀 Day 29 - 💡 JavaScript Tricky Question Explanation let a = [1,2,3]; delete a[1]; console.log(a); console.log(a.length); 👉 Output: ``` [1, empty, 3] 3 ``` 👉 Explanation: * `delete` removes the value but does NOT reindex the array * It creates a hole (empty slot) instead of shifting elements * So, `length` remains 3 ⚠️ Use `splice()` if you want to remove and shift elements #JavaScript #WebDevelopment #Frontend #CodingInterview #JSConcepts

🚀 Day 23 - Poll answer & Explanation 💡 **JavaScript Event Loop Explained (Simple & Clear)** ```javascript console.log('S'); Promise.resolve().then(() => console.log('P1')); setTimeout(() => console.log('T1'), 0); Promise.resolve().then(() => console.log('P2')); setTimeout(() => console.log('T2'), 0); console.log('E'); Output: S E P1 P2 T1 T2 ``` 🔹 **Explanation:** * `S` and `E` run first → synchronous code (call stack) * `P1`, `P2` → microtasks (Promises) → run next * `T1`, `T2` → macrotasks (setTimeout) → run last 👉 Microtasks always execute before macrotasks in the event loop. #JavaScript #ReactJS #WebDevelopment #Coding #FrontendDeveloper #InterviewPrep
