在turfjs中创建多个多边形的并集的最快方法是什么？

npm install turf turf-boolean-union

const turf = require('turf');
const booleanUnion = require('turf-boolean-union');

const polygon1 = turf.polygon([[[0, 0], [0, 10], [10, 10], [10, 0], [0, 0]]]);
const polygon2 = turf.polygon([[[5, 5], [5, 15], [15, 15], [15, 5], [5, 5]]]);
const polygon3 = turf.polygon([[[10, 0], [10, 10], [20, 10], [20, 0], [10, 0]]]);

const featureCollection = turf.featureCollection([polygon1, polygon2, polygon3]);

const union = booleanUnion(featureCollection);
