insert current element before previous one

Question

I'm checking to see if element is last in the container div by getting length on next element with class .item (if there is such element, it means that I am currently not at the end of the container div)

if($(this).next('.item').length < 1) {
  console.log('element is last');
}

In case if it is last, I want to move it up, i.e insert it before previous .item so it now becomes second last.

I looked into .insertBefore() , however I don't explicitly know which "before" element to target.

You can use the :last selector to get the last element in a matched set. From there you can use insertBefore() and prev() to move it as required. Try this:

var $last = $('.item:last');
$last.insertBefore($last.prev());
