Answer 1

As a beginner everyone tends to have doubts and you have a lot of them. Instead of asking too many questions at once, try doing a little bit of research on node.js so that you understand what exactly it is used for.

Youtube must have some really good content and similarly you can look for some websites which teach you this.
