How to call a specific function before and after every fetch api request and response

I want to call a function during sending a request and after receiving response with every fetch() function using Vanilla JS. I saw that jquery ajax is providing some kind of $.ajaxsetup for doing this but I want to do it with Vanilla JS. Thanks in advance.

fetch doesn’t have a feature like that. You could write a wrapper function though:

JavaScript

and then call that function instead of accessing fetch directly.
