Profiling jQuery event delegation performance issues in a large-scale application
I'm writing unit tests and Recently started profiling an application that relies heavily on jQuery for handling user interactions through event delegation. As the app scales, I've noticed some significant delays during event handling, especially when many elements are being dynamically added to the DOM. For example, I have this structure: ```javascript $(document).on('click', '.dynamic-button', function() { // some processing }); ``` While this seems to work, I've been reading that excessive event attachment can lead to performance bottlenecks. To mitigate this, I tried switching to a more specific parent when binding events, targeting a less frequently changing element instead of `document`, like so: ```javascript $('#parent-container').on('click', '.dynamic-button', function() { // some processing }); ``` To measure the impact, I utilized Chrome's DevTools for profiling the event handlers, and it showed a reduction in memory usage, but there are still noticeable lags when multiple users interact with the elements simultaneously. Given the dynamic nature of my application's UI, I'm curious if there are additional strategies to further optimize jQuery's event handling. Should I explore throttling or debouncing in this context, or are there best practices I might be missing? Also, any insights on using jQuery alongside modern frameworks like React or Vue in terms of performance would be valuable. Looking for a comprehensive approach to ensure smooth interactions across various devices. I'm using Javascript LTS in this project. This is for a application running on Windows 11. Cheers for any assistance!
