What is the Node.js Event Loop, and how does it work?
Aryan Kumar
28-Sep-2023The Node.js event loop is a crucial concept that underlies the asynchronous, non-blocking I/O nature of Node.js. It's at the heart of how Node.js manages concurrency and handles events efficiently. The event loop allows Node.js to perform I/O operations without blocking the execution of other code, making it highly performant and suitable for handling a large number of concurrent connections.
Here's how the Node.js event loop works:
The Node.js event loop, combined with its single-threaded, event-driven architecture, is what enables Node.js to efficiently handle thousands of simultaneous connections and perform I/O operations without blocking the execution of other code. It's a fundamental part of Node.js that developers need to understand to write scalable and performant applications in the platform.
