Fails to load on IE11

[mviens]

On IE11, the code does not load. The error is SCRIPT1003: Expected ':' on Line xxxx.

The code it is failing on is:

return {
    url,
    json,
    type
};

If the code is changed to the following, it will work:

return {
    url: url,
    json: json,
    type: type
};
