Welcome: Setting Up Node.js

Get ready to build your first WebSocket server! Our journey begins by setting up a new Node.js project. Node.js is a powerful JavaScript runtime that lets you run JavaScript code outside of a web browser.

This lesson will guide you through initializing your project and installing essential libraries.

node -v
npm -v
