SharePoint Email Functionlity -Javascript

I have a piece of code, used to send mail using SharePoint Mail utility function, which is working fine.

$.ajax({
    contentType: 'application/json',
    url: urlTemplate,
    type: "POST",
    data: JSON.stringify({
        'properties': {
            '__metadata': {
                'type': 'SP.Utilities.EmailProperties'
            },
            'From': from,
            'To': {
                'results': [to]
            },
            'Body': body,
            'Subject': subject
        }
    }),

I just want to know how can I send same with CCing some one.
