jQuery .animate() causing performance optimization on multiple elements with large DOM updates
I've spent hours debugging this and Quick question that's been bugging me - I'm working with a important performance scenario when using jQuery's `.animate()` method to transition multiple elements on my page. I have a list of items that are dynamically generated and need to animate their height when they are shown or hidden based on user interaction. The question is that when I try to animate these elements simultaneously, the browser becomes unresponsive, and I see a noticeable lag, especially on lower-end devices. Here's a simplified version of what I'm doing: ```javascript $(document).ready(function() { $('.toggle-button').on('click', function() { $('.list-item').each(function(index, element) { $(element).stop(true, true).animate({ height: $(element).is(':visible') ? '0px' : '50px' }, 400); }); }); }); ``` I'm currently using jQuery version 3.6.0, and the list can contain over 100 items. Each time I click the toggle button, all items change their height simultaneously, leading to the performance scenario. I've tried using `.stop(true, true)` to clear the animation queue, but it doesn’t seem to solve the lag. I also considered using CSS transitions instead but need help integrating that with my current jQuery logic. Would switching to a CSS-based approach significantly improve performance? And if so, how can I implement it while maintaining similar interactivity? Any advice or pointers on optimizing this would be appreciated! What's the correct way to implement this? I'm coming from a different tech stack and learning Javascript. Is there a simpler solution I'm overlooking?
