Access geojson key-value pairs that are not geometry or properties?

Question

    "type": "FeatureCollection",
    "features": [
        {
            "type": "Feature",
            "geometry": {
                "type": "Polygon",
                "coordinates": [
                    [
                        [
                            -77.155585,
                            40.056708,
                            0
                        ],
                        [
                            -77.150315,
                            40.04536,
                            0
                        ]
                    ]
                ]
            },
            "id": 42001030101,
            "Households": 1000,
            "Income": 74597
        },

I am using the google maps JS API. I cannot use the getProperty function because the data doesn't have the properties grouped together.

How can I access each of these pieces of data?

Here is what I tried before I realized that you can't use the properties function.

        map.data.setStyle(
          function(feature){
            let income = feature.getProperty('Income');
            let color = 'blue';
            if (income > 10000){
              color = 'red'
            }
            return {
              fillColor: color,
              //strokeColor: "green",
              strokeWeight: 0.3,
            };
          }
        );

According to the geojson spec :

A Feature object has a member with the name "properties". The value of the properties member is an object (any JSON object or a JSON null value).

As your feature doesn't have a properties member, you can 'repair' it so that any member that is neither type nor geometry is bundled as a member of properties .

This should enable your existing code using feature.getProperty() .

 const data = { "type": "FeatureCollection", "features": [ { "type": "Feature", "geometry": { "type": "Polygon", "coordinates": [ [ [-77.155585, 40.056708, 0], [-77.150315, 40.04536, 0] ] ] }, "id": 42001030101, "Households": 1000, "Income": 74597 } ] } const repairGeoJsonProps = (fc) => { return { "type": "FeatureCollection", "features": fc.features.map(ftr => { const props = Object.entries(ftr).filter(k => ["type", "geometry"].indexOf(k[0]) < 0); return { "type": ftr.type, "geometry": ftr.geometry, "properties": Object.fromEntries(props) } }) } } console.log(repairGeoJsonProps(data));
