期望返回的数据

// 期望返回这样的数据结构

        age: '30',
        parent: [
            {

简单版本

const csv = `
name,age,parent
Bob,30,David
David,60,
Anna,10,Bob
`;
function strTransformObj(str) {
    const firstArr = str.split(/\n|\r/g);
    firstArr.pop();
    firstArr.shift();
    const secondArr = firstArr.map((strItem) => {
        return strItem.trim().split(",");
    })
    return [{
        name: secondArr[1][0],
        age: secondArr[1][1],
        parent: [{
            name: secondArr[2][0],
            age: secondArr[2][1],
        }],
        children: [{
            name: secondArr[3][0],
            age: secondArr[3][1],
            parent: [{
                name: secondArr[1][0],
                age: secondArr[1][1],
            }]
        }]
    }]
    console.log(secondArr);
}
console.log(strTransformObj(csv));
