【JS面试题】深克隆 和 浅克隆 有了解过吗？能手写深克隆吗？

    let obj = {
        name: "前端猎手",
        des: "好好学习，天天向上",
        like: ["琴", "棋","书", "画"],

          name: "乔布斯",
          des:"神一样的男人",
          achievement:["苹果公司","皮克斯"]
        },
      };
      
    let newObj = {};

      function deepClone(origin, target) {
        var target = target || {}, //容错处理，防止用户不传target值

        for (let prop in origin) {
          //遍历对象
