How can I improve jQuery selector speed

Improving jQuery selector speed is crucial for optimizing web performance. By using simpler selectors, caching, and reducing the depth of the DOM tree you can achieve faster selectors.

// Example of improving jQuery selector performance $(document).ready(function() { // Cache the selector to improve speed var $items = $('.my-items'); // Do some operations with the cached selector $items.each(function() { $(this).css('color', 'blue'); }); // Direct child selector is faster than deep descendant selector var $directChildren = $('#parent > .child'); $directChildren.hide(); });
