JavaScript

Uncaught Type Error

Im new to ajax and Im doing some simple AJAX, JSON and jQuery however Im receiving this error message regarding my JSON file.

Uncaught TypeError: Cannot use 'in' operator to search for '150' in { "Question1": "What year did Henry join Arsenal", "Question2": "What team did Henry play for first", "Question3": "Where was Henry Born" }

Below is my Javascript files with the AJAX

$.ajax({ url: "questions.json", dataType: "json", type: "GET", success:function(data){ ( $.each(data, function(index, value) {
$('.question').text(value); alert(index.statusText); }, // end each

});
