Node2Know — HelloNode

The smallest possible Node.js program.

This repo is intentionally tiny so we can focus on the workflow:

• run a Node script from the terminal
• re-run it with Node’s built-in watch mode

---

✅ Prereqs

• Node.js installed (includes node)

Check your version:

node -v

---

▶️ Run the script

This repo contains a single file:

• app.js

Run it:

node app.js

You should see:

Hello, Node

---

👀 Run with watch mode

Node can automatically re-run your script when files change:

node --watch app.js

Now edit app.js (change the message), save, and watch Node re-run it.

To stop watch mode:

• Press Ctrl + C
