What is a node.js developer?

Question

Node.js

Hello, sorry for the stupid question.
Preface
The fact is that I'm used to CMS, in particular Drupal, and often different characters call themselves Drupal developers, although in fact they can simply deploy it and "create" it - how to shit, a couple of thousand-million cocoa sites, all that doing so is installing a base theme, installing prebuilt modules, and creating the nth number of fields. Tobish on this work ends.
So. As I meet characters from the Drupal universe, I began to meet similar ones called node.js developers. I mean, I basically got into the vacancies and didn’t understand anything, some write that it requires a banal understanding of what a node is, knowledge of js, jquery, bootstrap. Others write some cosmic things ...
And actually the question: to call yourself a node.js developer, you only need to be able to deploy it and use it as cms in a heap with a database?
Thank you, I hope I put the question correctly, if anything, I'm sorry (I can't get enough sleep for a month, so I can say something stupid
) The question is wildly principled to those floating in this environment. Personally, I do not work with a node, but there is an understanding of what it is in general.

Node.js is not a web server or CMS, it's just a JavaScript runtime where you can do anything (including write your own web server, framework, etc.). To be called a Node.js developer, you need to understand the intricacies of asynchronous JS, know most of the built-in functions of Node.js, be able to work with the main modules and create your own.
In the context of front-end development, they usually only want a person to be able to install it and configure the builder. This is not a Node.js developer.
