Wait ajax to complete before continue loop

I’ve modified my codes based on Jory Hogeveen comments, and it solved my problem. What I do is, to not using the regular loop but instead use a recursive function that calls itself after it finishes calling for the request. For those who are looking for the same answer, please see below.

var users_info = <?php echo json_encode($usersarray); ?>;
console.log(users_info);
$=jQuery;
var each="";
    j = 0;
    function nextAjax(i) {
        var data = {
            'action': 'delete_orphan_users',
            'user_id': users_info[i]
        };
        $.post(ajaxurl, data, function(response) {
            n = new Date($.now());
            m = n.getHours()+':'+n.getMinutes();
            $("#status").prepend(m+' '+response);
            j++;
            $("#deletedusers").html(j);
            if( j==users_info.lenght ){
                location.reload(); //current batch finished, reload screen to get another batch of users
            } else {
                nextAjax(j);
            }
        });
    }
    console.log('Start')
    nextAjax(j);
