I use turf.lineIntersect method to get the intersection of the two line,
i got result is

{"type":"FeatureCollection","features":[{"type":"Feature","properties":{},"geometry":{"type":"Point","coordinates":[120.539991319355,31.32943431295146]}}]}

the result seems not match in geojson.io ..

        const line1 = [
            [120.179402, 31.247428, 0],
            [120.700497, 31.365937, 0]
        ]

        const line2 = [
            [120.445638, 31.381745, 0],
            [121.033588, 31.055778, 0],
            [121.094159, 31.046175, 0],
            [121.167627, 31.042088, 0]
        ]

        const point = intesection(line1, line2)

        console.log(JSON.stringify(point));
        function intesection(lineString1, lineString2) {

            const line1 = turf.lineString(lineString1)
            const line2 = turf.lineString(lineString2)

            var intersects = turf.lineIntersect(line1, line2);

            return intersects
        }
