Node.js

Node.js is a powerful, open-source JavaScript runtime that allows developers to build fast, scalable server-side applications. By using an event-driven, non-blocking I/O model, Node.js handles high-performance applications efficiently, making it ideal for web servers, APIs, and real-time applications like chat apps. Learning Node.js equips developers with the ability to use JavaScript for both front-end and back-end development, simplifying full-stack development. Mastering Node.js also opens doors to working with popular frameworks like Express.js and integrating databases like MongoDB, making it a crucial skill for modern web developers.
