Returned value for $.when.apply($, $.map(array, someFunction(x){}))?

Question

What is returned from getTickets function?

function getTickets(needsTickets) {
    return $.when.apply($, $.map(needsTickets, function(x) {
        return function(x) { return $.ajax() } ;
    }));
}

Answer 1

Let's analyze what is happening:

The result of $.when is a promise and that is what is being returned.

$.when doesn't accept an array as arguments so to handle an array of promises you need to do:

$.when.apply( context, promiseArray);

The promise array is being created by $.map
