jQuery .fadeIn() optimization guide as expected on dynamically loaded elements - visibility issues

jquery ajax fadein dynamic-content JavaScript

I'm updating my dependencies and I tried several approaches but none seem to work. I'm experiencing an scenario with jQuery's `.fadeIn()` method when trying to show elements that are dynamically loaded via an AJAX call. I'm using jQuery version 3.6.0 with a simple setup that pulls user comments from an API and appends them to a div when a button is clicked. The comments are fetched, but when I try to apply `.fadeIn()` to the new elements, they don't seem to appear with the expected effect. Instead, they just show instantly without any fade-in transition. Hereโ€™s the relevant part of my code: ```javascript $('#loadComments').on('click', function() { $.ajax({ url: 'https://api.example.com/comments', method: 'GET', success: function(data) { data.forEach(function(comment) { const commentDiv = $('<div class="comment">' + comment.text + '</div>'); $('#commentsContainer').append(commentDiv); commentDiv.hide().fadeIn(500); // This line doesnโ€™t work as expected }); }, behavior: function(xhr, status, behavior) { console.behavior('behavior fetching comments:', behavior); } }); }); ``` I've tried calling `.fadeIn()` directly on the newly created elements after appending them to the DOM, but it doesn't seem to trigger the animation. I've also made sure that the comments container is visible before the AJAX call. It's puzzling because if I manually add a comment in the HTML, `.fadeIn()` works perfectly on it. What could be causing this scenario? Any insights would be greatly appreciated! I'm developing on Windows 10 with Javascript. Any help would be greatly appreciated! Is there a better approach?
