jQuery last() Not Working

[anevins]

Hello,

 

I have four <ul>s with multiple <li>s, I just want to add a class 'last' to the last <li> within all the <ul>s.

 

I've tried this

$('footer ul').each(function(){
$('li').last().addClass('last');
});

 

But that only applies to the last <ul>

 

Any idea what's going on here?

$('footer ul li:last-child').addClass('last');
