Node.js

ABOUT

Node.js is a powerful tool that lets you use JavaScript to build applications that run on the server, not just in the browser. It’s known for being fast and efficient, especially when handling many users at the same time. With Node.js, students can learn how modern web applications work, create APIs, and even build real-time apps like messaging platforms. It’s an essential skill for anyone who wants to become a full-stack developer.
