js中实现将原对象赋值给新对象

 <script>
        var object = {
            username:'jack',
            age:'18',
            id:'1123'
        }
        //方法一es6扩展符
        var nob = {...object}
        //方法二for..in遍历原对象
        // for(let key in object){
        //     console.log(key);
        //     console.log(object[key]);
        //     nob[key]= object[key]
        // }
      console.log(nob);
    </script>
