Explain a bit more

creates the order. pp.use(express.json()); pp.get('/api/users', (req, res) => { res.json([{ id: 1, name: 'Alice' }]); }); pp.listen(3000, () => console.log('Server running')); pp.use(express.json()); pp.get('/api/users', (req, res) => { res.json([{ id: 1, name: 'Alice' }]); }); pp.listen(3000, () => console.log('Server running')); Real-world example… (ShopNest) Express middleware authenticates JWT, then the /orders route handler creates the order.

Say this in the interview

2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
