How to read the code?

Hello !

Tell me so how do you correctly read the code? A function inside a function inside a variable with two arguments ... If it's right to read, just mind-blowing ! 10 minutes read a different "sauce", It's something ...

Language JS if that....

Recommendations ..links..publication.. personal opinion ... would be grateful!

Read until blue in the face:
To understand the language. Loops, arrays, functions, ways of solving a particular problem, and more.
Having mastered one thing - practice. For example knew what a cycle - open Codepen and create for yourself such as 10 tasks.

For example toggle the active class when clicking on menu items and so on.

Nothing comes easy, especially learning programming languages.

Good luck.
