Question

Node.js

I am learning vue.js and express.js. vue.js took as frontend and express.js. There was a question that both have a router, and I can’t understand which one to use or uses them under different circumstances. I'm trying to write a blog, I took mysql as a base.

express frontend - backend are
two different things, with two different routers.
They have nothing to do with each other, just two different things.
learn the materiel what is front and back.

Answer 2

express is a server-side solution that processes requests to the server along certain paths accordingly.
vue - handles routes on the client, allowing navigation without reloading the page.
