js 把二维数组改成四象限图用的格式

function quadrantSort(arr) {
    let quadrant1 = [];
    let quadrant2 = [];
    let quadrant3 = [];
    let quadrant4 = [];

    arr.forEach(point => {
        if (point[0] > 0 && point[1] > 0) {
            quadrant1.push(point);
        } else if (point[0] < 0 && point[1] > 0) {
            quadrant2.push(point);
        } else if (point[0] < 0 && point[1] < 0) {
            quadrant3.push(point);
        } else if (point[0] > 0 && point[1] < 0) {
            quadrant4.push(point);
        }
    });

    return {
        quadrant1,
        quadrant2,
        quadrant3,
        quadrant4
    };
}

const points = [[-1, 1], [1, 2], [-1, -1], [1, -1]];
const sortedPoints = quadrantSort(points);

console.log('Quadrant 1:', sortedPoints.quadrant1);
console.log('Quadrant 2:', sortedPoints.quadrant2);
console.log('Quadrant 3:', sortedPoints.quadrant3);
console.log('Quadrant 4:', sortedPoints.quadrant4);
