Demystifying Node

Node.js Basics (Theory) | Event Loop, Async Operations & Core Concepts Explained In this video, we explore the core theoretical concepts of Node.js that every developer must understand before building backend applications. Instead of just coding, this tutorial focuses on how Node.js actually works under the hood. 💡 Topics covered in this video: What is Node.js and why it’s different from traditional backend technologies Understanding single-threaded architecture Deep dive into the Event Loop Synchronous vs Asynchronous operations Non-blocking I/O and how Node.js handles multiple requests Callbacks, Promises, and Async/Await (conceptual overview) Role of V8 Engine in executing JavaScript How Node.js achieves scalability 🧠 Why this matters: Many beginners jump straight into coding without understanding the internal working of Node.js. This video builds your strong conceptual foundation, which is crucial for writing efficient, scalable, and production-ready backend systems.
