You can use the :last pseudo-selector:

$('#test div.a:last')

Without jQuery:

var divs = document.getElementById("test").getElementsByTagName("div");
var lastChild = divs[divs.length - 1];

$('div#test div:last-child');

using the proposed at

const nodesHighlighted = document.querySelectorAll('.day--highlight');
const lastNodeHighlighted = [...nodesHighlighted].at(-1);

at the current writing it's not supported by safari
