var poly = {
  'type': 'Feature',
  'properties': {},
  'geometry': {
    'type': 'Polygon',
    'coordinates': [[[125, -30], [145, -30], [145, -20], [125, -20], [125, -30]]]
  }
}
var lines = turf.polygonToLineString(poly);
//addToMap
var addToMap = [lines]

Returns FeatureCollection<(LineString | MultiLinestring)> converted Feature to Lines
