How to inspect - log variable from js of website u visit?

1

I want to see data of variables of desired website
So I tried to download full page and to add logs but then I got CORS.
Server does not have jsonp feature

Did you try to inspect the element?
Then from inside the console, check out the Sources section. It usually shows the js file.

that was my ‘very’ first attempt

Did it not work?
What site were you looking at?

No matter what target is, i asked globally

when u open js file.in sources, u cant inspect variables, in case u dont put `debugger;` in code + i cant use browser console cause in my case vatiable doesnt have global reference nor some kind nested reference

I’m sorry. This must be beyond my scope of knowledge.
I hope someone else can provide the answer.
