How to create an array from AJAX response

Question

All seems like it should be very simple but I am having issues.

I would like to create an array and list all 'questions' within the array from an AJAX response using jQuery.

I gather my thinking is out as question just returns a higher level object containing all data.

var questions = response.questions;
console.log(response.questions);

var question = [
  $.each(questions, function (value) {
   value.question
  })
];

What does response.questions look like?

Assuming that response looks like this:

{
    questions: [
        {question: 'A'},
        {question: 'B'},
        {question: 'C'}
    ]
}

and you want

['A', 'B', 'C']

then .map() is what you are looking for.

var question = $.map(response.questions, function (item) {
   return item.question;
});

How would I then map the index of the questions to get, ['0' , '1' , '2'] for example?

I'm not sure what you mean by that. The index is provided as the second argument to the .map() callback, if you need it for anything. (Next time, please ask a complete question. Input sample, corresponding desired output and a short paragraph of what you intend to do in the bigger picture. Debugging an incomplete question via the comment section is tedious and overall very inefficient.)

You can do something like this:

var questions = response.questions;
console.log(response.questions);    

question = []
for(var q of questions){
    question.push(q)
}
