when to use $(this) and e.target?

I don't have confusion for $(this), but e.target for me is confusing because it can perform the same thing as $(this). (or I'm wrong?)

```
$(document).on('click',"div", function(){
        $(this).css('color', 'red');
    }
});

```

vs

```
$(document).on('click',"div", function(e){
        $(e.target).css('color', 'red');
    }
});

```
