⚙️ Event Loop in Node.js: How It Works and Why It Matters

Node.js is known for its non-blocking, asynchronous nature, making it highly efficient for handling multiple requests. At the core of this behavior lies the event loop, which allows Node.js to perform non-blocking I/O operations efficiently. In this post, we will break down what the event loop is, how it works in Node.js, and why it is essential.
