      "geometry": {

              [

                  116.447661,

              ]
          ]
      }
  }
  ]
}

The two lines have an approximate intersection point, but I cannot get the intersection point using lineIntersect.

my code

  const line1 = lineString([
    [
      116.352264,
      39.86083
    ],
    [
      116.507446,
      39.931158
    ]
  ]);
  const line2 = lineString([[
    116.507446,
    39.931158
  ],
  [
    116.525642,
    39.959058
  ]
  ]);
  console.log('res', lineIntersect(line1, line2));
