The ParentNode.lastElementChild read-only property returns the object's last child Element or null if there are no child elements.

Note: This property was initially defined in the ElementTraversal pure interface. As this interface contained two distinct set of properties, one aimed at Node that have children, one at those that are children, they have been moved into two separate pure interfaces, ParentNode and ChildNode. In this case, lastElementChild moved to ParentNode. This is a fairly technical change that shouldn't affect compatibility.


const element = node.lastElementChild


<ul id="foo">
  <li>First  (1)</li>
  <li>Second (2)</li>
  <li>Third  (3)</li>

const foo = document.getElementById('foo');
console.log(foo.lastElementChild.textContent); // logs: Third (3)


The code below adds support of lastElementChild() to Document and DocumentFragment in Internet Explorer and Safari.

// Overwrites native 'lastElementChild' prototype.
// Returns array instead of HTMLCollection.
;(function(constructor) {
  if(constructor &&
    constructor.prototype &&
    constructor.prototype.lastElementChild == null) {
    Object.defineProperty(constructor.prototype, 'lastElementChild', {
      get: function() {
        var node, nodes = this.childNodes, i = nodes.length - 1;
        while(node = nodes[i--]) {
          if(node.nodeType === 1) {
            return node;
        return null;
})(window.Node || window.Element);


Specification Status Comment
The definition of 'ParentNode.lastElementChild' in that specification.
Living Standard Splitted the ElementTraversal interface in ChildNode and ParentNode. This method is now defined on the latter.
The Document and DocumentFragment implemented the new interfaces.
