Как найти длину кривой Безье, и точки на ней через равные промежутки?

const subtract = (v1, v2) => ({
  x: v1.x - v2.x,
  y: v1.y - v2.y
});

const magnitude = ({ x, y }) => Math.sqrt(x * x + y * y);


const pointDistance = (point1, point2) => magnitude(subtract(point1, point2));


const curveLength = (points) => {
  let lastPoint = points[0];
  const pointsSansFirst = points.slice(1);
  return pointsSansFirst.reduce((acc, point) => {
    const dist = pointDistance(point, lastPoint);
    lastPoint = point;
    return acc + dist;
  }, 0);
};
