Can I use only javascript as the back-end of a stie?

Answer 1

With Node.js and express.js you can implement the backend logic.

Answer 2

I believe JavaScript is a front-end not a back-end though this can be made possible using node.js

You can use php or python for back-end.

Answer 3

Yes, with node.js you can. :)

Answer 4

Yes, using node.js that runs on npm, u can achieve that
