求数组中任意三个点的面积最大的值

  function aeraS(points) {
      let res = [];
      for (let i= 0;i< points.length-2; i++) {
        for (let j = i+1; j < points.length-1; j++) {
          for (let k = 0; k < points.length; k++) {
            // S=(x1y2-x1y3+x2y3-x2y1+x3y1-x2y2)。
            res.push(points[i][0]*points[j][1]-points[i][0]*points[k][1]
            // +x2y3-x2y1
            +points[j][0]*points[k][1]-points[j][0]*points[i][1]
            // +x3y1-x2y2
            +points[k][0]*points[i][1]-points[j][0]*points[j][1])
          }
        }
      }
      res = res.sort((a,b)=>b-a)
      console.log(res);
      return res[0]
    }
    console.log(aeraS([[0,0],[0,1],[1,0],[0,2],[2,0]]));
