Javascript and Node
As a beginner, it's hard to get to a point where you are confident enough in your programming abilities.
While learning to code, you might also be confused at where does JavaScript end, and where Node.js begins, and vice versa.
I would recommend you to have a good grasp of the main JavaScript concepts before diving into Node.js:
Lexical Structure
Expressions
Types
Variables
Functions
this
Arrow Functions
Loops
Scopes
Arrays
Template Literals
Semicolons
Strict Mode
ECMAScript 6, 2016, 2017
With those concepts in mind, you are well on your road to become a proficient JavaScript developer, in both the browser and in Node.js.
The following concepts are also key to understand asynchronous programming, which is one fundamental part of Node.js:
Asynchronous programming and callbacks
Timers
Promises
Async and Await
Closures
The Event Loop
