Please check PR https://github.com/googlemaps/js-markerclusterer/pull/419
there was comment from my side and [davidpadych](https://github.com/davidpadych)

Code example
export default class BoundingSuperClusterAlgorithm extends SuperClusterAlgorithm {
cluster({ map }) {
const bounds: any = map.getBounds().toJSON();
const boundingBox: any = [
bounds.west,
bounds.south,
bounds.east,
bounds.north,
];
const transform = this.transformCluster.bind(this);

return this.superCluster
.getClusters(boundingBox, Math.round(map.getZoom()))
.map(transform);
}
}
