Has anyone noticed... preventDefault() works without passing in the parameter in this case?

$(document).ready(function(){
    $("a").click(function(event){//andrew shows us this way
        event.preventDefault();
    });
});

$(document).ready(function(){
    $("a").click(function(){//but this seems to work as well
        event.preventDefault();
    });
});

I'm not using jQuery on a regular basis, but the point is you get 2 different objects back (depending on if event is passed to the function or not). In your case you can access the preventDefault() method either way, so it doesn't matter.

It's not the same, but in this case it doesn't matter.

Check out this fiddle

Run it and open your console to see the difference.

I ran it, looked at the console...but I don't know what I'm looking at. I guess you're saying in other or most circumstances we need to pass a parameter or something bad will happen.
