What knowledge is needed to learn Node.JS?
Good day. I want to learn javascript, but in many places it is advised to look towards node.js . So the question arose of how deep knowledge of javascript should be in order to learn node . Or do not waste time and just learn js well now?

If you know what routes, event loop, scope, callback are, you know how to debug js, you know how GET differs from POST request, then "go ahead, be a hero!", as they say.
Seriously though, telling someone new to JavaScript to start with node.js is pretty dumb.
To write code in Node.JS with a deep understanding of what is happening, you need to understand how the OS works (sending messages, multiplexing, ...). Also, the server part is practically meaningless without a database, so you need to know at least MySQL (although I think MongoDB is more popular for Node.JS).
I hope I won’t be downvoted if I write that browser JS is different and there, for the most part, you need to think differently and about completely different things.
I think, knowledge of simple JS will not be enough.
If you love node, why not start learning JS while trying to write something on node?
You are going to use JS somewhere later, right? :)
Node is convenient incl. as an environment for learning JavaScript. Closer to the console, more distractions in the browser. In the past, many people started learning languages with console projects.
