Using JavaScript to effectively handle my JSON data

I've been trying to retrieve the data from my JSON file, but I keep getting an error in the console that says "Uncaught TypeError: Cannot read property 'longitude' of undefined." This method is new to me and I would really appreciate any help you can offer. Thank you!

var data = [];

     $(document).ready(function(){
     $.ajax({
         url: 'http://******',
         type: 'get',
         dataType: 'JSON',
         success: function(response){         

           data.push(response);
         }

     });

 });

 console.log(data[1].longitude);

It seems like your code is asynchronous, which is why when you try to console log your variable, it appears empty. To fix this issue, you should move the console.log inside the success function.

var recuptable = [];

     $(document).ready(function(){
     $.ajax({
         url: 'http://******',
         type: 'get',
         dataType: 'JSON',
         success: function(response){         
           console.log(response.longitude);
           recuptable.push(response);
         }

     });

 });

Furthermore, I recommend learning more about callbacks and promises to become proficient in working with asynchronous code.
