jquery performance animation resize JavaScript

I've hit a wall trying to I've spent hours debugging this and Quick question that's been bugging me - I am experiencing a performance scenario when using jQuery's `.animate()` method on a set of elements during the window resize event. The animation seems to be lagging significantly when the window is resized quickly, which is particularly noticeable on lower-end devices. Here’s the relevant part of my code: ```javascript $(window).on('resize', function() { $('.box').animate({ width: $(window).width() / 2 }, 300); }); ``` I’ve tried debouncing the resize event to mitigate the lag: ```javascript let debounce; $(window).on('resize', function() { clearTimeout(debounce); debounce = setTimeout(function() { $('.box').animate({ width: $(window).width() / 2 }, 300); }, 100); }); ``` However, I still notice choppy animations and sometimes, the layout appears to flicker as if the dimensions are being calculated incorrectly. I'm using jQuery version 3.6.0 and testing this in the latest version of Chrome. The flickering seems to happen especially when the resizing is rapid. Is there a better approach to handle this kind of situation without sacrificing performance? Should I consider using CSS transitions instead for smoother animations? Any insights or best practices would be greatly appreciated! For context: I'm using Javascript on Windows. I'm coming from a different tech stack and learning Javascript. Any pointers in the right direction? Is there a better approach?
