Self-reference within a JavaScript object involves creating a property that points

Can you reference another part of a JSON object within the same JSON object?

In the code snippet below, there is an object that refers to the "home" object within the "MapParameters" 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 it possible to reference part of a JSON object in this way, and if so, how should it be done?

Answer №1

Sorry, but JSON does not support circular references, however, JavaScript objects do allow for circular references. This limitation exists because circular structures are not serializable:

let obj = {};
obj.x = obj;
console.log(JSON.stringify(obj));
