示例

🌐 Examples

var line = turf.lineString([
  [0, 0],
  [0, 2],
  [0, 5],
  [0, 8],
  [0, 8],
  [0, 10],
]);
var multiPoint = turf.multiPoint([
  [0, 0],
  [0, 0],
  [2, 2],
]);

turf.cleanCoords(line).geometry.coordinates;
//= [[0, 0], [0, 10]]

turf.cleanCoords(multiPoint).geometry.coordinates;
//= [[0, 0], [2, 2]]
