jquery mobile touch-events JavaScript

I'm deploying to production and While developing a cross-platform mobile app using jQuery Mobile, I've noticed that touch events are noticeably lagging, especially when trying to implement custom swipe gestures. The app is intended to work seamlessly across both iOS and Android devices, but the current experience feels sluggish on older devices. I've implemented basic touch event handlers like this: ```javascript $(document).on('touchstart', function(event) { // Handle touch start }); $(document).on('touchmove', function(event) { // Handle touch move }); $(document).on('touchend', function(event) { // Handle touch end }); ``` However, during testing, the swipe gestures are not as responsive as I expected. I’ve tried optimizing the event handling by preventing default behavior: ```javascript $(document).on('touchmove', function(event) { event.preventDefault(); // Prevent scrolling // Handle touch move logic }); ``` This worked somewhat, but the lag still persists on some devices, particularly when there are multiple event bindings. I've also read about using `fastclick.js` to eliminate the 300ms delay on mobile browsers, and while that helped with click responsiveness, I still face issues with touch events. Is there a recommended strategy to improve the performance of touch event handling in jQuery? Are there specific techniques, like throttling or debouncing events, that could help mitigate the lag? More importantly, how do I ensure these changes maintain compatibility across the various platforms my app targets? Any insights or example implementations would be greatly appreciated! I've been using Javascript for about a year now. What would be the recommended way to handle this?
