Scroll to bottom of div?

Question

I am creating a chat using Ajax requests and I\'m trying to get messages div to scroll to the bottom without much luck.

I am wrapping everything in this div:

I use the difference between the Y coordinate of the first item div and the Y coordinate of the selected item div. Here is the JavaScript/JQuery code and the html:

function scrollTo(event){
        // In my proof of concept, I had a few s with value 
        // attributes containing strings with id selector expressions
        // like "#item1".
        let selectItem = $($(event.target).attr('value'));
        let selectedDivTop = selectItem.offset().top;

        let scrollingDiv = selectItem.parent();

        let firstItem = scrollingDiv.children('div').first();
        let firstItemTop = firstItem.offset().top;

        let newScrollValue = selectedDivTop - firstItemTop;
        scrollingDiv.scrollTop(newScrollValue);
    }
