.new Group()

Sometimes you need to make groups of objects (it's not conveniently to apply transforms to each object when can make just one to a group).
In Three.js you make it using THREE.Object3D and it's children.

In whs.js we have Group

Examples

Approach 2 - Adding objects to an empty group

const sphere = new Sphere();
const box = new Box();
const group = new Group();

sphere.addTo(group);
box.addTo(group);

Approach 2 - Making a group from objects

const sphere = new Sphere();
const box = new Box();
const group = new Group(box, sphere);
// OR: const group = new Group([box, sphere]);
