In jQuery, is it faster to check if an element exists before trying to bind event handlers?

Question

Is it faster to first check if an element exists, and then bind event handlers, like this:

if( $(\'.selector\').length ) {
    $(\'.selector\').on(\'click\',         


        

Answer 1

Just use

$('.selector').on('click',function() {
     // Do stuff on click
}

If no elements exist with the class selector, jQuery will simply not bind anything.
