Optimizing jQuery for a CI/CD Pipeline with Heavy DOM Manipulations

During development, I've noticed that our CI/CD pipeline becomes significantly slower when deploying features that involve heavy DOM manipulations with jQuery. We are utilizing jQuery 3.6.0, and while we've implemented some caching strategies, performance still lags. One area I'm focusing on is how to optimize event bindings and AJAX handling without compromising the user experience. I've started by switching to event delegation for elements added dynamically, yet the performance isn't improving as expected. This snippet demonstrates my current approach: ```javascript $(document).on('click', '.dynamic-button', function() { $.ajax({ url: '/api/getdata', method: 'GET', success: function(data) { // Update DOM with data } }); }); ``` Initially, I thought that delegating the click event would alleviate some of the performance issues. However, profiling using Chrome's DevTools shows that the bottleneck occurs during the AJAX calls, particularly when handling large responses. I've tried reducing data size on the server side, but the response time is still a concern. Additionally, I'm considering whether using `$.when` to handle multiple AJAX requests could streamline the process, although I'm unsure how it’ll impact the overall performance. Here’s my current attempt at using it: ```javascript $.when( $.ajax('/api/getdata1'), $.ajax('/api/getdata2') ).done(function(data1, data2) { // Process both responses }); ``` Has anyone tackled similar issues efficiently? Any best practices for optimizing jQuery in a CI/CD context, especially when it comes to AJAX performance and event handling? Any insights into managing large data sets or leveraging jQuery utilities for improved performance would be greatly appreciated. Thanks! The project is a REST API built with Javascript. Any ideas how to fix this?
