示例1: point
import { polygon, point, featureCollection, geometryCollection, Feature, Polygon, FeatureCollection } from '@turf/helpers';
import rotate from './'
const pt = point([15, 15]);
const poly = polygon([[[0,29],[3.5,29],[2.5,32],[0,29]]]);
// Does not mutate Geometry type
const rotatedPoly: Feature<Polygon> = rotate(poly, 100, {pivot: pt});
const rotatedFCPoly: FeatureCollection<Polygon> = rotate(featureCollection([poly]), 100, {pivot: pt});
// Different Geometry Inputs
rotate(poly, 100, {pivot: pt});
