Why put Jquery events in a separate .js file?

Question

WordPress

Friends, tell me, do they always take out the jquery code of events and so on (click, submit) in a separate .js file?
What are the best rules to follow?
A lot of php-parameters are passed to the jquery code. Parameters can only be passed by setting onclick=""?
Thanks in advance.

Answer 1

Need to know the address for notification of incoming payments or transfers to the server address?

Answer 2

How convenient to do so. But probably if you want order, then build a modular structure. For example, using RequireJS: habrahabr.ru/post/152833
How is it transmitted?
The easiest and most convenient option is to make data-* attributes on the element and read them when the event fires.
