如何提取高度嵌套的对象里的指定属性？

function findKey(data, field) {let finding = "";for (const key in data) {if (key === field) {finding = data[key];}if (typeof data[key] === "object") {finding = findKey(data[key], field);}if (finding) {return finding;}}return null;
}//测试
console.log(findKey({name: "zhangsan",age: 19,stuInfo: {stuNo: 1,classNo: 2,score: {htmlScore: 100,cssScore: 90,jsScore: 94,},},},"cssScore")
);
