distance-to-polygon

• a point p# is represented as a list like this : const p1 = [x = 0, y = 0];

• f(x) is a transformation function applied to the result :

    const roundToTwoDecimal = (x) => Math.round(x * 100) / 100;
    distanceBetweenPoints(p1, p2, roundToTwoDecimal);

• distanceBetweenPoints(p1, p2, f = (x) => x)

• distanceToLine(point, line, f = (x) => x)
  • const line = [p1, p2];

For polygons, make sure the vertices are listed clockwise or counter-clockwise.

• distanceToPolygon(point, vertices, f = (x) => x)
  • const vertices = [p1, p2, p3, …];
