Explain how Angular.js and node.js work?

Question

JavaScript

I'm just learning and I still can't understand a lot of things. And here is one of them.
Just now I was reading the documentation and tutorials on Angular.js, on the official website. It was written there that this tool does SPA from A to Z, that is, the server too. Node.js also makes the server, what is the difference between these technologies? I tried this and that (according to the guides), I’m interested in this and that and I understand that on knowledge only of JS I won’t swim far, so I want to master some of these technologies, but I can’t determine what the difference is.
Thanks for the replies, I hope I made myself clear.

Answer 1

Angular.js only works on the browser side.
In most cases, this very SPA will need to interact with the server, for this you will need an API that can be written both in node.js and other technologies.
What you write about is full stack js frameworks, they just consist of both client (browser) and server parts.
