@arcgis/core/geometry/operators/centroidOperator
Calculates the centroid for a 2D geometry. The centroid represents the geometric center of mass, where the mass is equally distributed at each point/vertex of the geometry. For example, the centroid of a straight line is the midpoint. The centroid of a point is the point itself. It is not guaranteed to be within or on the geometry. The centroid of a donut polygon is the center of the hole, which is outside the polygon. The centroid of a curved polyline is not located on the line itself, but will be some distance away from it.
