How can the code be optimized using JQuery for better performance and maintainability?
One way to optimize code using jQuery for better performance and maintainability is to minimize the use of DOM manipulation by selecting elements once and storing them in variables for reuse. This reduces the number of times the DOM needs to be traversed, improving performance. Additionally, using event delegation can help reduce the number of event handlers attached to individual elements, making the code easier to maintain. ```javascript // Example of optimizing code using jQuery $(document).ready(function() { // Select elements once and store them in variables var $button = $('#myButton'); var $input = $('#myInput'); // Event delegation to handle events on dynamically added elements $('body').on('click', '#myButton', function() { var value = $input.val(); console.log('Input value: ' + value); }); }); ```
