In order: set up the environment, write your first program with console.log, use built-in modules like fs and http, build a basic HTTP server, learn modules with module.exports and require, install Express, build a REST API, and connect a database and auth.
Start with console.log('Hello from Node.js') to confirm it works, then try requiring built-in modules like os or fs to access system information. This shows what server-side JavaScript can do that browser JavaScript cannot.
After you have built a basic HTTP server with the http module and understand modules. Express handles routing, middleware, and request parsing, so understanding what it does under the hood first makes Express more meaningful.
