jQuery .append() causing unexpected duplication of elements in IE11

jquery ie11 append dom-manipulation JavaScript

I'm learning this framework and I'm experiencing an scenario where using jQuery's .append() method is causing elements to duplicate unexpectedly in Internet Explorer 11. Specifically, I have a list that I am dynamically populating with items based on user input, but when I call .append() to add new items, it's adding them multiple times instead of just once. Here is a simplified example of my code: ```javascript $(document).ready(function() { $('#addItem').on('click', function() { var newItem = $('#newItemInput').val(); if (newItem) { $('#itemList').append('<li>' + newItem + '</li>'); $('#newItemInput').val(''); } }); }); ``` I have confirmed that the `#addItem` button is not triggering multiple clicks because I've added a console log that only outputs once per click. However, in IE11, when I check the DOM after adding an item, I can see that the new list item gets added more than once. I also tried using `.html()` instead of `.append()`, but it completely wipes out the existing list. Is there something specific to IE11's handling of the DOM that I need to consider? Any insights or possible workarounds would be greatly appreciated! The project is a REST API built with Javascript.
