示例

var point1 = turf.point([-75.343, 39.984], {"marker-color": "#F00"});
var point2 = turf.point([-75.534, 39.123], {"marker-color": "#00F"});

var bearing = turf.rhumbBearing(point1, point2);

//addToMap
var addToMap = [point1, point2];
point1.properties.bearing = bearing;
point2.properties.bearing = bearing;
