Passing parameters in laravel?

Question

JavaScript

public function update(Request $request, $id)
{
//
}
also seen a lot in JS and wrote
click(e)
What is e ?
As I see it, these are arguments, but we didn’t pass them anywhere,
in Laravel, as I understand it, we catch these arguments somewhere there ...... or is this similarity as in js?
And what is this E (I understand that the element) and where does it come from?

Answer 1

e is short for event. This parameter comes by default, for example, when you hang events on dom elements.

document.querySelector('button').addEventListener('click', (event) => {
    console.log(event);
});
