Load more than one GeoJSON?

Cesium ion
1

I am currently using this code to load in one GeoJSON:
var dataSource = Cesium.GeoJsonDataSource.load(
‘http://localhost:5050/tilesets/TestFolder/CensusDivisions.geojson’,
{
stroke: Cesium.Color.WHITESMOKE,
fill: Cesium.Color.WHITE.withAlpha(0.1),
strokeWidth: 6,
}
);
viewer.dataSources.add(dataSource);
If I just copy and paste this only the first one will load. Will I be able to load multiple GeoJSONs into different layers to be loaded at once? Sort of like roads/buildings footprints/municipal boundaries to be visualized at once
