Differences between express.Router and app.get?

Question

I\'m starting with NodeJS and Express 4, and I\'m a bit confused. I been reading the Express website, but can\'t see when to use a route handler or when to use

Answer 1

using app.js to write routes means that they are accessible to all the users as app.js is loaded on application start. However, putting routes in express.router() mini apps protect and restrict their accessibility.
