IE doesn’t support remove() native Javascript function but does
support removeChild().

Browser compatibility for remove()

Solution n°1

Use remove() in pure Javascript you can declare it yourself with this following code :

// Create Element.remove() function if not exist
if (!('remove' in Element.prototype)) {
    Element.prototype.remove = function() {
        if (this.parentNode) {
            this.parentNode.removeChild(this);
        }
    };
}
// Call remove() according to your need
child.remove();

As you can see the function get the parent node of element and then remove this element from his parent with removeChild() native function.

Solution n°2

Use removeChild() in pure JavaScript on all browser including IE just call it insteed of remove().

element.removeChild(child);

Solution n°3

Use jQuery through code.jquery.com CDN by using this following code :

<!-- Include jQuery -->
<script
  src="https://code.jquery.com/jquery-3.2.1.min.js"
  integrity="sha256-hwg4gsxgFZhOsEEamdOYGBf13FyQuiTwlAQgxVSNgt4="
  crossorigin="anonymous"></script>
<!-- Use remove() -->
<script>
child.remove();
</script>

The function is included in the jQuery library so you can call it after inclusion.

Happy coding ! 🙂
