Just use a button

Weird, I always use buttons when I can, unless what I need is not actually a button, but something that performs and on-click sort of like a button, like a hyperlink that navigates you through the web app.

I guess if it doesn't update the url, it's a button.

If it changes the url, it should be a link. At least that's how I've always done it.

Is is not okay to wrap a link inside a button ? I guess not

Which elements are allowed to wrap which is unclear to me
