The Easiest Node.js (Global ver.)

🛑 This course is an English-based lecture targeted at non-Korean speakers.

💪 Developers who understand the internals are always more powerful.

Many developers programming in the Node.js environment tend to focus solely on learning frameworks, often missing out on the principles and structure of Node.js itself.

This course covers the core concepts and built-in modules of Node.js—from the differences between CommonJS and ES Modules to the event loop, file system, network handling, and multiprocessing—through practical code examples. It helps you naturally understand how the internals of libraries and frameworks are structured.

If you’re someone who wants to go beyond simply writing working code and understand why it works that way, this course will be the most solid starting point for you. Build the confidence to implement a server with just Node.js—without frameworks—and create your own tools.

😀 Yalco’s lectures are special.

📌 Features of This Course

• Learn by directly implementing Node.js core concepts.
  You can understand the operational principles of Node.js—such as the module system, event loop, processes, and streams—through hands-on practice.

• Naturally grasp the internal structure of frameworks.
  By starting from the basics of Node.js, you can trace and understand how frameworks like Express or NestJS are built.

• Composed of immediately executable examples.
  Rather than focusing on theoretical explanations, you’ll gain practical skills through real-world examples like building servers, handling files, and managing network communication.
