126. Understanding stdin, stdout, stderr in Node.js | Streams, Buffers & Terminal I/O Explained

In this video, we explore how Node.js handles input and output using standard streams: stdin, stdout, and stderr. You'll learn how to read input from the terminal, write output and errors, and how these streams relate to Unix concepts. We'll also show you how to redirect outputs to files and understand how console.log() is just a wrapper for process.stdout.

🔍 What you'll learn:

What are stdin, stdout, and stderr in Node.js
How to use streams to read input and write output
How to structure cleaner code with destructuring
How console.log() works under the hood
How to redirect output to files using shell commands
The link between Node.js and low-level C functions like printf
How to replace console with custom output streams
📁 Includes terminal demos, code walkthroughs, and real-world examples.
