What knowledge is needed to learn Node.JS?

Question

JavaScript

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?

Answer 1

Of course, JS needs to be well studied first.

Answer 2

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.

Answer 3

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.

Answer 4

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? :)

Answer 5

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.
