+/**
+ * Takes two {@link Point|points} and returns a point midway between them.
+ * The midpoint is calculated geodesically, meaning the curvature of the earth is taken into account.
+ *
+ * @name midpoint
+ * @param {Coord} point1 first point
+ * @param {Coord} point2 second point
+ * @returns {Feature<Point>} a point midway between `pt1` and `pt2`
+ * @example
+ * var point1 = turf.point([144.834823, -37.771257]);
+ * var point2 = turf.point([145.14244, -37.830937]);
+ *
+ * var midpoint = turf.midpoint(point1, point2);
+ *
+ * //addToMap
+ * var addToMap = [point1, point2, midpoint];
+ * midpoint.properties['marker-color'] = '#f00';
