getting json data jquery with .get

<script> 
      $.get("url", function(data, textStatus, jqXHR) {
      var json = JSON.stringify(data);
      });
 // I would like to use **json** variable here
</script>

Hey, I would like to get data from url. I can get the JSON file and stringify it to json variable. But I have some struggles when I 'm trying to use json variable. Because, it is local variable. Also, 

 <script> 
     var json = "";
     $.get("url", function(data, textStatus, jqXHR) {
     json = JSON.stringify(data);
     });
 // I would like to use **json** variable here
</script>

when I am trying to use json as a global variable, even I can not stringify data to it.

Question : How can I solve my problem?

It would be better to use your JSON data when it is available by putting the dependent code in a callback or a promise:

$.getJSON("url").then(function(data) {
  // json is already parsed here
  // put json dependent code here
});

You could also put your application logic in a function (assuming it's depending on the JSON data) and use that as your callback:

function initialize(data) {
   // all of your data dependent logic here
}

$.getJSON("url").then(initialize);
