Course Summary

Node.js is a practical, hands-on course designed to teach students how to build scalable, event-driven applications using JavaScript on the server.

Students learn Node.js from a production and systems perspective—focusing on asynchronous programming, the event loop, modular design, and building real-world services and APIs. The course emphasizes how Node.js behaves under load, how to structure applications cleanly, and how to avoid common pitfalls when working with async code.

By the end of the course, students are comfortable reading, writing, debugging, and deploying Node.js applications and understand how Node fits into modern backend, cloud, and DevOps ecosystems.
