How you should not write code | JavaScript

Thanks for your feedback. That I what I am trying to highlight. You can write similar code based on your needs. You don’t need to follow certain standards. For some, developer they like more concise code than well-structured code. I prefer the second part. Coz I love functional programming. So that is natural.

Regarding, the private variable I just highlighted. You may not need this now. With the help of a new private scope variable. Underscore will be going to obsolete. And more than it helps, it creates confusion. If you dont use it correctly.
