How to level up my nodejs?

Question

JavaScript

This is a cry of despair. There is a project on nodejs (browser engine), but the farther into the forest, the greater the understanding that I don’t know some things that those who really understand and know how to develop on node.js are silent about. There are more and more questions for which there are no answers. What tasks to solve to improve the skill, what to read, etc.

Answer 1

Node.js Design Patterns

Answer 2

you would specify what exactly you have problems with, what you already know, etc.
In general, I recommend that you become more familiar with the principles of functional programming.
