Ken, you can make a synchronous request with XMLHttpRequest if you need to
(though it's not commonly done):
var request = new XMLHttpRequest();
request.open('GET', 'data.json', false); // false implies synchronous
request.responseType="json";
request.send(null);
But do consider the option of making an asynchronous request and putting
the rest of your code in the request callback function so it executes only
when the data has loaded.
