Event delegation is a technique where you attach an event handler to a parent element, and then use the on() method to handle events that occur on its child elements. This can be more efficient than attaching event handlers to individual child elements, especially if there are many of them. For example, to handle click events on all buttons within a container element with the ID “myContainer”, you would use the following code:

$('#myContainer').on('click', 'button', function() {
// code to handle the click event
});

By using event delegation, you can handle click events on all buttons within the container element, even if new buttons are added dynamically in the future.
