The bufio package in Go makes reading input simple and efficient.
In this video, I show you how to use bufio.NewReader with:

📂 Files

🌐 TCP connections

⌨️ Standard Input (stdin)

You’ll also see how ReadString('\n') works and why buffered I/O is so useful when handling text, logs, or network data.

bufio is a small but powerful tool in Go:
✅ Works with files, sockets, and stdin
✅ Efficient buffered reading
✅ Easy to use for many real-world cases

Perfect for anyone learning Go who wants to handle input the right way.
