How can I change an array with multiple fields in a row into an array with just one?

Question

I have this data in a javascript variable:

var a = {
  "answers":[
     {"correct":null, "response":true, "text":"x" },
     {"correct":null, "response":true, "text":"y" }
  ]
}

I would like to send this to the server but exclude the correct and text fields. How can I remove these?

Try this

var result = a.answers.map(function(obj){return {response:obj.response}})

Here result will be an array of objects having just response field.

Thanks. I did try map but now I realize I probably did not do it correctly. I will try your suggestion.
