Javascript Object internal self referencing

Is there a way to reference another portion of a JSON object inside of the same JSON object?

I have an object below that makes a reference in the "MapParameters" object to the "home" object. 

{
"parameters": {
    "data": {
        "URL": "http://SC.json",
        "name": "SC"
    },
    "MapParameters": {
        "center": [home.lat, home.lng],
        "zoom": home.zoom,
        layers: [streets, layers]
    },
    "basemap": {
        "basemapsText": {
            "<span class='pointer'>Streets</span>": "streets",
            "<span class='pointer'>Satellite</span>": "aerial"
        }
    "other": {
        "scale": {
            "maxWidth": 200,
            "metric": true,
            "imperial": true
        },
        "home": {
            lat: 37.26,
            lng: -93.53,
            zoom: 7
        }
    }
}

Is this possible, and if so, how is it written?

No, you cannot have circular references in JSON, but you can have circular references in JavaScript objects. The reason this is, is because it's not serializable:

let o = {};
o.a = o;
console.log(JSON.stringify(o));
