Is each needed on click event (simple code inside)?

Question

JavaScript

Elementary question.
Both codes work fine, but which one is better? I don't understand if each is needed?

$('.apply_button, .canget').click(function(e) {
// код
});

$('.apply_button, .canget').each(function(){
        $(this).click(function(e) {
// код
        }):
}):

There are many buttons with both classes on the page.

Answer 1

when clicking each, in any case, it will be superfluous. if the elements on the page were originally - use the first click option. if they are dynamically added to the dom, then use the following construct:

$(document).on('click', '.apply_button, .canget', function(e) {
  // код
  });
