Reasonable use of an event handler?

Question

JavaScript

Colleagues, I have a question.
If I need to hang a lot of code on, for example, scroll, what is the best way to do this?
Push everything into one handler, or break it into separate small blocks $('...').on('scroll',function(){...}).
Or is there no difference?

Answer 1

If it is necessary that all code be executed, then it is better in one. And if it executes only part of the code, and ignores the other, then it is better to break it.
