Smallest example: app.get + next(). Type it, run it, and say what you see. If you can do that from memory, you know Difference between Node.js and Express js.

From the example next to this theory — Difference between Node.

Trap — wrong middleware order. Fix that before you talk about advanced Node.js.

Viva — what is Difference between Node.js and Express js? Then show app.get + next(). Then name the trap.

Exam tip

What is Difference between Node.js and Express js? Show this: app.get + next(). Trap: wrong middleware order.

Example

const http = require("http");

const server = http.createServer((req, res) => {
  res.writeHead(200, { "Content-Type": "application/json" });
  res.end(JSON.stringify({ ok: true, path: req.url }));
});

// server.listen(3000);
console.log("handler ready for", "/api/health");
console.log(JSON.stringify({ ok: true, path: "/api/health" }));

Difference between Node.js and Express js — http.createServer handles each request with (req, res). Express sits on top of this.
