How to await ALL of the Listeners execution for Custom jQuery Event?

Question

$(document).on('custom-event', listener1 );
$(document).on('custom-event', listener2 );

function listener1() {
    return new Promise((resolve) => {
        setTimeout(resolve, 3000);
    })
}

function listener2() {
    return new Promise((resolve) => {
        setTimeout(resolve, 10000);
    })
}


$(document).trigger('custom-event');
const afterAwaiting = true; // Need to await 10 seconds after previous line of code to execute this statement

I've triggered custom Event - custom-event.

Need to await All of the Listeners execute its code,

then continue to execute next statement.

Answer 1

I've found solution by using when.

await $.when( $(document).trigger('custom-event') )

const afterAwaiting = true;

jQuery runs Custom Events Synchronously according to the question

jQuery trigger custom event synchronously?

Or it works even without await

$(document).trigger('custom-event')
