Sequentially
if you are talking about the almost obsolete native javascrtipt function prompt()
then:
var array=[];questions=['A?','B?','C?'],current=0;
function q(question){
array.push(prompt(question,'write here')+' question number:'+current);
if(current<questions.length){
next()
}else{
array.sort()// needs a proper sort function
alert(array.join("\n"));
};
}
function next(){
q(questions[current++]);
}
next();
